This is the patch of testcases for the ext4 new features test. It contains multi-block alloc/delayed alloc test, inode version test, journal checksumming test, nanosec timestamps test, online defrag test, persist prealloc test, subdirectory limit test and uninit groups test of ext4. In this test suite, there is two FAIL in the subdirectory limit test. It is because we cann't create more than 32000 subdirectory when block size is small, such as 1024, and the name of every subdirectory is very long, such as every name is 255 bytes. I think it is the bug of the ext4.
Note: Your MUST run configure in the directory testcases/kernel/fs/ext4-new-features to config the tool of ffsb, and specify a partition to be used for test before compiling the tool. The data on the specified partition would be DESTROYED.

+TEST SUITE:
+
+The directory ext4-new-features contains the tests related to the ext4
+filesystem's new features.
+
+Ext4 is an advanced level of the ext3 filesystem which incorporates scalability
+and reliability enhancements for supporting large filesystems(64 bit) in keeping
+with increasing disk capacities and state-of-the-art feature requirements. More
+extensive information of ext4 can be found at the ext4 wiki site at the URL:
+http://ext4.wiki.kernel.org
+
+There are total 119 testcases for ext4 new features test that have been added.
+Now, these testcases can test multi-block alloc/delayed alloc, inode version
+field on disk, journal checksumming, nanosec timestamps, online defrag, persist
+prealloc, subdirectory limit and uninit groups of ext4.
+The detail information of ext4 new features can be found at the URL:
+http://ext4.wiki.kernel.org/index.php/New_ext4_features
+
+
+TESTS AIM:
+
+The aim of the tests is to test ext4 new features.
+
+
+TEST STEPS:
+# cd LTPROOT/testcases/kernel/fs/ext4-new-features
+# ./configure
+# make
+# make install
+# cd LTPROOT
+# ./runltp -f fs_ext4
+
+**This testsuite wouldn't be built when doing LTP default build. We MUST do it
+ by ourself.
+
+
+NOTE:
+
+1. This test can be run by root only.
+2. Your MUST run *configure* in this directory to config the tool of ffsb and
+ specify a partition to be used for test before compiling the tool, and be
+ CAREFUL the data on the specified partition would be DESTROYED. It is better
+ that the size of partition is between 5G and 10G. If the partition is too
+ big, the test will spend much time. It is unnecessary.
+3. Before starting test ext4 new features, please check whether ext4 filesystem
+ is compiled into the kernel or not, and the kernel version is *2.6.31* or
+ above.
+4. A snapshot of config file options is given below:
+ ONFIG_EXT4_FS=y
+ CONFIG_EXT4DEV_COMPAT=y
+ CONFIG_EXT4_FS_XATTR=y
+ CONFIG_EXT4_FS_POSIX_ACL=y
+ CONFIG_EXT4_FS_SECURITY=y
+
+5. Beside that, the following packages are necessary:
+ e2fsprogs
+ (http://www.rpmfind.net/linux/rpm2html/search.php?query=e2fsprogs)
+ e2fsprogs-devel
+ (http://www.rpmfind.net/linux/rpm2html/search.php?query=e2fsprogs-devel)
+ e2fsprogs-libs
+ (http://www.rpmfind.net/linux/rpm2html/search.php?query=e2fsprogs-libs)
+ and the version of these packages should be 1.41.4 or above, otherwise the
+ test will fail.
+
+
+FILES DESCRIPTION:
+
+configure
+---------
+This is a config script that is used to configure the ffsb tool and specify a
+partition for test. And the data on the specified partition would be destroyed.
+Be careful! Beside that, you MUST run this script before compile the testcases.
+
+ext4-delalloc-mballoc
+---------------------
+Directory containing the shell script which is used to test multi-block
+allocation and delayed allocation of ext4.
+
+ext4-ffsb-config
+----------------
+Directory containing the config of ffsb for test.
+
+ext4-inode-version
+------------------
+Directory containing the shell script which is used to test inode version field
+on disk of ext4.
+
+ext4-journal-checksum
+---------------------
+Directory containing the shell script which is used to test journal checksumming
+of ext4.
+
+ext4-nsec-timestamps
+--------------------
+Directory containing the shell script which is used to test nanosec timestamps
+of ext4.
+
+ext4-online-defrag
+------------------
+Directory containing the shell script which is used to test online defrag
+feature of ext4.
+
+ext4-persist-prealloc
+---------------------
+Directory containing the shell script which is used to test persist prealloc
+feature of ext4.
+
+ext4-subdir-limit
+-----------------
+Directory containing the shell script which is used to test subdirectory limit
+of ext4. According to the kernel documentation, we create more than 32000
+subdirectorys on the ext4 filesystem.
+
+But, when then block size is small, such as 1024, and the name of every
+subdirectory is very long, such as every name is 255 bytes, we can just create
+less than 20000 subdirectory. In this test suite, there is two FAIL cases by
+reason of it.
+
+ext4-uninit-groups
+------------------
+Directory containing the shell script which is used to test uninitialized groups
+feature of ext4.
+
+ffsb-6.0-rc2
+------------
+This directory contains The Flexible Filesystem Benchmark (FFSB) tool. We use
+this tool to create some files to fill the test partition. This tool was written
+by Sonny Rao(raosanth@us.ibm.com).
+
+ext4_funcs.sh
+-------------
+This script contains some functions for ext4 new features test script.
+such as: ext4_setup, ext4_cleanup
+
+run_ext4_test.sh
+----------------
+This script runs all the 119 testcases.
+
+Makefile
+--------
+Each directory in this directory has its usual makefile, it is for its
+directory.
+
+README
+------
+The one you have gone through.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory. After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Introduction:
+
+The Flexible Filesystem Benchmark (FFSB) is a filesystem performance
+measurement tool. It is a multi-threaded application (using
+pthreads), written entirely in C with cross-platform portability in
+mind. It differs from other filesystem benchmarks in that the user
+may supply a profile to create custom workloads, while most other
+filesystem benchmarks use a fixed set of workloads.
+
+As of version 5.1, it supports seven different basic operations, support
+for multiple groups of threads with different operation mixtures,
+support for operation across multiple filesystems, and support for
+filesystem aging prior to benchmarking.
+
+
+Differences from version 4.0 and older:
+
+Version 5.0 and above represent almost a total re-write and many
+things have changed. In version 5.0 and above FFSB moved to a
+time-regulated run versus doing a set number of different operations
+and timing the whole thing. This is primarily to better deal with the
+use of multiple threadgroups which would otherwise not be synchronized
+at termination time.
+
+Additionally, the FFSB configuration file format has changed in
+version 5.0, although we do support old-style configuration files
+along with a run-time passed on the command line. In this mode,
+version 5.0 and above ignores the iterations parameter, and simply
+uses the time specified on the command line.
+
+Behaviorally, most of the old operations are the same -- sequential
+reads and sequential writes work as they did before. One change in
+version 5.0 is the skip-read behavior of reading then seeking forward
+a fixed amount then reading again is removed, we now support fully
+randomized reads and writes from random offsets within the file.
+
+Version 4.0 didn't support overwrites (only appends) so we interpret
+writes in old config files to be append operations.
+
+On Linux, CPU utilization information will only be accurate for
+systems using NPTL, older Linuxthreads systems will probably only see
+zeros for CPU utilization because Linuxthreads is non-compliant to
+POSIX. Version 4.0 and older could be recompiled to work on
+Linuxthreads, but in 5.0 and later we no longer support this.
+
+We no longer support the "outputfile" on the command line.
+
+One should simply use tee or similar to capture the output. FFSB
+unbuffers standard out for this purpose, and errors are sent on
+standard error.
+
+Global options:
+
+There are eight valid global options placed at the beginning of the
+profile. Three of them are required: num_filesystems (number of
+filesystems), num_threadgroups (number of threadgroups), and time
+(running time of the benchmark). The other five options are:
+
+directio - each call to open will be made using O_DIRECT
+alignio - aligns all block operations for random reads and writes
+ on 4k boundaries.
+bufferedio - currently ignorred: it is intended to use libc
+ fread,rwrite, instead of just unix read and write calls
+verbose - currently ignored
+
+callout - calls and external command and waits for its termination
+ before FFSB begins the benchmark phase.
+ This is useful for synchronizing distributed clients,
+ starting profilers, etc.
+
+They must be specified in the above order (num_filesystems,
+num_threadgroups, time, directio, alignio, bufferedio, verbose,
+callout).
+
+
+
+Filesystems:
+
+Filesystems are specified to FFSB in the form of a directory. FFSB
+assumes that the filesystem is mounted at this directory and will not
+do any verification of this fact beyond ensuring it can read/write to
+the location. So be careful to ensure something with enough space to
+handle the dataset is in fact mounted at the specified location.
+
+In the filesystem clause of the profile, one may set the starting
+number of files and directories as well as a minimum and maximum
+filesize for the filesystem. One may also specify the blocksize
+used for creating the files separately in the filesystem clause.
+
+Also, if a filesystem is to be aged, a special threadgroup clause may
+be embedded in a filesystem clause to specify the operation mixture
+and number of threads used to age the filesystem. This threadgroup is
+run until filesystem utilization reaches the specified amount.
+
+Inheritance -- if you are using multiple filesystems, all attributes
+except the location should be inherited from the previous filesystem.
+This is done to make it easier to add groups of similar filesystems.
+In this case, only the location is required in the filesystem clause.
+
+As of version 5.1, filesystem re-use is supported if a given
+filesystem hasn't been modified beyond it's orginal specifications
+(number of files and directories is correct, and file sizes are within
+specifications). This can be a huge time saver if one wishes to do
+multiple runs on the same data-set without altering it during a run,
+because the fileset doesn't need to be recreated before each run.
+
+To do this, specify "reuse=1" in the filesystem clause, and FFSB will
+verify the fileset first, and if it checks out it will use it.
+Otherwise, it will remove everything and re-create the filesets for
+that filesystem.
+
+Threadgroups:
+
+An arbitrary number of threadgroups with differing numbers of threads
+and operation mixes can be specified. The operations are specified
+using a weighting for each operation, if an operation isn't specified
+it's weighting is assumed to be zero (not used).
+
+"Think-time" for a threadgroup may also be specified in millisecond
+amounts using the "op_delay" parameter, where every thread will wait
+for the specified amount between each operation.
+
+Operations:
+
+All operations begin by randomly selecting a filesystem from the list
+of filesystems specified in the profile. The distribution aims to be
+uniform across all filesystems.
+
+
+The seven operations are:
+
+reads - read() calls with an overall amount and a blocksize
+ operates on existing files. Care must be taken to ensure
+ that the read amount is smaller than the size of any possible
+ file.
+
+ If random_read is specified, then the each individual blocks
+ will be read starting from a random point with the file, and
+ this will continune until the entire amount specifed has been
+ read. This offset of each random block will be totally
+ random to the byte level, unless the "alignio" global parameter
+ is on, and then the reads will be 4096 byte aligned. This is
+ generally recommended.
+
+
+readall - Very similar to read above, except it doesn't take an
+ amount; it simply reads the entire file sequentially using the
+ read_blocksize. This is useful for situations where
+ different filesystems have differently sized files, and sequential
+ read patterns across all filesystems are desired.
+
+writes - write() calls with an overall amount and blocksize
+ this is an overwrite operation and will not enlarge an existing
+ file, again one must be careful not to specify a write amount
+ that is larger than any possible file in the data set.
+
+ If random_write is specified, then the each individual blocks
+ will be written starting from a random point with the file, and
+ this will continune until the entire amount specifed has been
+ written out. This offset of each random block will be totally
+ random to the byte level, unless the "alignio" global parameter
+ is on, and then the writes will be 4096 byte aligned. This
+ is generally recommended.
+
+ If the fsync_flag parameter for the threadgroup is non-zero,
+ then after all of the write calls are finished, fsync() will
+ be called on the file descriptor before the file is closed.
+
+
+creates - creates a file using open() call and determines the size
+ randomly between on the constraints (min_filesize and
+ max_filesize) for the selected filesystem. Write operations will
+ be done using the same blocksize as is specified for the
+ write operation.
+deletes - calls unlink() on a filename and removes it from the
+ internal data-structures. One must be careful to ensure
+ there are enough files to delete at all times or else the benchmark
+ will terminate.
+appends - calls write() using the append flag with an overall amount
+ and a blocksize to be appended onto a randomly chosen file.
+metas - this is actually a mix of several different directory
+ operations. Each "meta" operation consists of two directory
+ creates, one directory remove, and a directory rename.
+ These operations are all carried out separately from the
+ other 5 operations.
+
+Operation accounting:
+
+Each operation which uses a blocksize counts each read/write of a
+blocksize as an operation (reads,writes,creates, and appends) whereas
+deletes and metas are considered single operations.
+
+Running the benchmark:
+
+There are three phases to running the benchmark, aging, fileset
+creates, and the benchmark phase.
+
+The create phase is carried out across all filesystems simultanously
+with one dedicated thread per filesystem.
+
+After the create phase, sync() is called to ensure all dirty data gets
+written out before the benchmark phase begins, and sync() is again
+called at the end of the benchmark phase. The time in sync() at the
+end of the benchmark phase is counted as part of the benchmark phase.
+
+Caveats/Holes/Bugs:
+
+Aging and aging across multiple filesystems simultaneously hasn't been tested
+very much.
+
+If *any* i/o operation or system call/libc call fails, the benchmark
+will terminate immediately.
+
+The parser doesn't handle mal-formed or incorrect profiles very well
+(or at all).
+
+The parser doesn't check to make sure all of the appropriate options
+have been specified. For example, if writes are specified in a
+threadgroup but write_blocksize isn't specified, the parse won't catch
+it, but the benchmark run will fail later on.
+
+
+Configuration Files (new style):
+
+New Style Configuration allows for arbitrary newlines between lines,
+and comments using '#' at the start of a line. Also it allows tabs,
+whitespace before and after configuration parameters.
+
+The new style configuration file is broken up into three main parts:
+
+global parameters, filesystems, and threadgroups
+
+The sections must be in the above order.
+
+Global parameters:
+
+Global Paramters are described above, the first three are always
+required. Example:
+
+----------
+
+num_filesystems=1
+num_threadgroups=1
+time=30 # time is in seconds
+
+directio=0 # don't use direct io
+alignio=1 # align random IOs to 4k
+bufferedio=0 # this does nothing right now
+verbose=0 # this does nothing right now
+
+ # calls and external command and waits
+ # everything until the newline is taken
+ # so you can have abritrary parmeters
+callout=synchronize.sh myhostname
+
+---------
+
+All of these must appear in this order, though you can leave out the
+optional ones.
+
+Filesystems:
+
+Filesystems describe differnt logical sets of files residing in
+different directorys. There is no strict requirement that they
+actually be on different filesystems, only that the directory
+specified already exists.
+
+Filesystems are specified by a clause with a filesystem number like
+this:
+
+[filesystem0]
+ location=/mnt/testing/
+ num_files=10
+ num_dirs=1
+ max_filesize=4096
+ min_filesize=4096
+[end0]
+
+
+The clause must always begin with [filesystemX] and end with [endX]
+where X is the number of that filesystem.
+
+You should start wiht X = 0, and increment by one for each following
+filesystem. If they are out of order, things will likely break.
+
+The required information for each filesystem is: location, num_files,
+num_dirs, max_filesize, and min_filesize. Beyond those the following
+four options are supported:
+
+
+
+reuse=1 # check the filesystem to see if it is reusable
+
+ # filesystem aging, three components required
+ # takes agefs=1 to turn it on
+ # then a valid threadgroup specification
+ # then a desired utilization percentage
+
+agefs=1 # age the filesystem according to the following threadgroup
+ [threadgroup0]
+ num_threads=10
+ write_size=40960
+ write_blocksize=4096
+ create_weight=10
+ append_weight=10
+ delete_weight=1
+ [end0]
+desired_util=0.20 # In this case, age until the fs is 20% full
+
+create_blocksize=4096 # specify the blocksize to write()
+ # for creating the fileset, defaults to 4096
+
+age_blocksize=4096 # specify the blocksize to write() for aging
+
+
+Also, to allow lazy people to use lots of filesystems, we support
+filesystem inheritance, which simply copies all options but the
+location from the previous filesystem clause if nothing is specified.
+Obviously, this doesn't work for filesystem0. (May not work for aging
+either?)
+
+Full blown filesystem clause example:
+
+----
+
+[filesystem0]
+
+ # required parts
+
+ location=/home/sonny/tmp
+ num_files=100
+ num_dirs=100
+ max_filesize=65536
+ min_filesize=4096
+
+ # aging part
+ agefs=0
+ [threadgroup0]
+ num_threads=10
+ write_size=40960
+ write_blocksize=4096
+ create_weight=10
+ append_weight=10
+ delete_weight=1
+ [end0]
+ desired_util=0.02 # age until 2% full
+
+ # other optional commands
+
+ create_blocksize=1024 # use a small create blocksize
+ age_blocksize=1024 # and smaller age create blocksize
+ reuse=0 # don't reuse it
+[end0]
+
+
+
+--
+
+Threadgroups:
+
+Threadgropus are very similar to filesystems in that any number of
+them can be specified in clauses, and they must be in order starting
+with threadgroup0.
+
+Example:
+
+---
+
+[threadgroup0]
+ num_threads=32
+ read_weight=4
+ append_weight=1
+
+ write_size=4096
+ write_blocksize=4096
+
+ read_size=4096
+ read_blocksize=4096
+[end0]
+
+---
+
+In a threadgroup clause, num_threads is required and must be at least
+1. Then, at least one operation must be given a weight greater than 0
+to be a valid threadgroup. Operations can be given a weighting of 0,
+and in this case they are ignored.
+
+Certain operations will also require other commands, for example, if
+read_weight is greater than zero, then one must also include a
+read_size and a read_blocksize. Here's the table of requirements and
+options:
+
+
+Operation Requirements Options
+-- -- --
+read_weight read_size, read_blocksize read_random
+readall_weight read_blocksize none
+write_weight write_size, write_blocksize write_random,fsync_file
+create_weight write_blocksize or create_blocksize none
+append_weight write_blocksize, write_size none
+delete_weight none none
+meta_weight none none
+
+
+
+Other threadgroup options:
+
+op_delay=10 # specify a wait between operations in milli-seconds
+
+bindfs=3 # This allows you to restrict a threadgroup's operation
+ # to a specific filesystem number. Currently only
+ # binding to one specific filesystem is supported
+

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+ * Container class for a red-black tree ......
+ *
+ * A binary tree that satisfies the following properties:
+ *
+ * 1. Every node is either red or black
+ * 2. The root node is black
+ * 3. Every leaf (NIL) is black
+ * 4. If a node is red, both its children are black
+ * 5. For each node, all paths from the node to descendant leaf nodes
+ * contain the same number of black nodes
+ *
+ * Due to points 4 & 5, the depth of a red-black tree containing n nodes
+ * is bounded by 2*log2(n+1) (WC).
+ *
+ *
+ * The rb_tree template requires two additional parmeters:
+ *
+ * - The contained TYPE class represents the objects stored in the tree.
+ * It has to support the copy constructor and the assignment operator (opr)
+ * - cmp is a functor used to define the order of objects of class TYPE:
+ * This class has to support an operator() that recieves two objects from
+ * the TYPE class and returns a negative, 0, or a positive integer,
+ * depending on the comparison result.

+The Flexible Filesystem Benchmark (FFSB) is a filesystem performance measurement tool. It is a multi-threaded application (using pthreads), written entirely in C with cross-platform portability in mind. It differs from other filesystem benchmarks in that the user may supply a profile to create custom workloads, while most other filesystem benchmarks use a fixed set of workloads.
+
+It is currently known to support Linux, AIX, and Solaris, although almost all development and testing has occurred on Linux. We intend to add support for HP-UX, IRIX, and possibly others in the near future.
+
+FFSB is currently at version 5.0, and has been an internal tool at IBM for about four years. I has already been used to conduct a study of Linux Kernel 2.6 IO-schedulers, and a great deal of future filesystem performance work is planned with FFSB as the primary tool.
+
+In version 5.0, it supports six different basic operations, support for multiple groups of threads with different operation mixtures, support for operation across multiple filesystems, and support for filesystem aging prior to benchmarking.
