Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 update from Ted Ts'o:
"Lots of bug fixes, cleanups and optimizations. In the bug fixes
category, of note is a fix for on-line resizing file systems where the
block size is smaller than the page size (i.e., file systems 1k blocks
on x86, or more interestingly file systems with 4k blocks on Power or
ia64 systems.)
In the cleanup category, the ext4's punch hole implementation was
significantly improved by Lukas Czerner, and now supports bigalloc
file systems. In addition, Jan Kara significantly cleaned up the
write submission code path. We also improved error checking and added
a few sanity checks.
In the optimizations category, two major optimizations deserve
mention. The first is that ext4_writepages() is now used for
nodelalloc and ext3 compatibility mode. This allows writes to be
submitted much more efficiently as a single bio request, instead of
being sent as individual 4k writes into the block layer (which then
relied on the elevator code to coalesce the requests in the block
queue). Secondly, the extent cache shrink mechanism, which was
introduce in 3.9, no longer has a scalability bottleneck caused by the
i_es_lru spinlock. Other optimizations include some changes to reduce
CPU usage and to avoid issuing empty commits unnecessarily."

4. Enumeration and Discovery
----------------------------
-When rio_init_mports() is called it scans a list of registered master ports and
-calls an enumeration or discovery routine depending on the configured role of a
-master port: host or agent.
+4.1 Overview
+------------
+
+RapidIO subsystem configuration options allow users to specify enumeration and
+discovery methods as statically linked components or loadable modules.
+An enumeration/discovery method implementation and available input parameters
+define how any given method can be attached to available RapidIO mports:
+simply to all available mports OR individually to the specified mport device.
+
+Depending on selected enumeration/discovery build configuration, there are
+several methods to initiate an enumeration and/or discovery process:
+
+ (a) Statically linked enumeration and discovery process can be started
+ automatically during kernel initialization time using corresponding module
+ parameters. This was the original method used since introduction of RapidIO
+ subsystem. Now this method relies on enumerator module parameter which is
+ 'rio-scan.scan' for existing basic enumeration/discovery method.
+ When automatic start of enumeration/discovery is used a user has to ensure
+ that all discovering endpoints are started before the enumerating endpoint
+ and are waiting for enumeration to be completed.
+ Configuration option CONFIG_RAPIDIO_DISC_TIMEOUT defines time that discovering
+ endpoint waits for enumeration to be completed. If the specified timeout
+ expires the discovery process is terminated without obtaining RapidIO network
+ information. NOTE: a timed out discovery process may be restarted later using
+ a user-space command as it is described later if the given endpoint was
+ enumerated successfully.
+
+ (b) Statically linked enumeration and discovery process can be started by
+ a command from user space. This initiation method provides more flexibility
+ for a system startup compared to the option (a) above. After all participating
+ endpoints have been successfully booted, an enumeration process shall be
+ started first by issuing a user-space command, after an enumeration is
+ completed a discovery process can be started on all remaining endpoints.
+
+ (c) Modular enumeration and discovery process can be started by a command from
+ user space. After an enumeration/discovery module is loaded, a network scan
+ process can be started by issuing a user-space command.
+ Similar to the option (b) above, an enumerator has to be started first.
+
+ (d) Modular enumeration and discovery process can be started by a module
+ initialization routine. In this case an enumerating module shall be loaded
+ first.
+
+When a network scan process is started it calls an enumeration or discovery
+routine depending on the configured role of a master port: host or agent.
Enumeration is performed by a master port if it is configured as a host port by
assigning a host device ID greater than or equal to zero. A host device ID is

-outlined in the RapidIO Interconnect Specification: Annex I [1].
+4.2 Automatic Start of Enumeration and Discovery
+------------------------------------------------
+
+Automatic enumeration/discovery start method is applicable only to built-in
+enumeration/discovery RapidIO configuration selection. To enable automatic
+enumeration/discovery start by existing basic enumerator method set use boot
+command line parameter "rio-scan.scan=1".
+
+This configuration requires synchronized start of all RapidIO endpoints that
+form a network which will be enumerated/discovered. Discovering endpoints have
+to be started before an enumeration starts to ensure that all RapidIO
+controllers have been initialized and are ready to be discovered. Configuration
+parameter CONFIG_RAPIDIO_DISC_TIMEOUT defines time (in seconds) which
+a discovering endpoint will wait for enumeration to be completed.
+
+When automatic enumeration/discovery start is selected, basic method's
+initialization routine calls rio_init_mports() to perform enumeration or
+discovery for all known mport devices.
+
+Depending on RapidIO network size and configuration this automatic
+enumeration/discovery start method may be difficult to use due to the
+requirement for synchronized start of all endpoints.
+
+4.3 User-space Start of Enumeration and Discovery
+-------------------------------------------------
+
+User-space start of enumeration and discovery can be used with built-in and
+modular build configurations. For user-space controlled start RapidIO subsystem
+creates the sysfs write-only attribute file '/sys/bus/rapidio/scan'. To initiate
+an enumeration or discovery process on specific mport device, a user needs to
+write mport_ID (not RapidIO destination ID) into that file. The mport_ID is a
+sequential number (0 ... RIO_MAX_MPORTS) assigned during mport device
+registration. For example for machine with single RapidIO controller, mport_ID
+for that controller always will be 0.
+
+To initiate RapidIO enumeration/discovery on all available mports a user may
+write '-1' (or RIO_MPORT_ANY) into the scan attribute file.
+
+4.4 Basic Enumeration Method
+----------------------------
+
+This is an original enumeration/discovery method which is available since
+first release of RapidIO subsystem code. The enumeration process is
+implemented according to the enumeration algorithm outlined in the RapidIO
+Interconnect Specification: Annex I [1].
+
+This method can be configured as statically linked or loadable module.
+The method's single parameter "scan" allows to trigger the enumeration/discovery
+process from module initialization routine.
+
+This enumeration/discovery method can be started only once and does not support
+unloading if it is built as a module.
The enumeration process traverses the network using a recursive depth-first
algorithm. When a new device is found, the enumerator takes ownership of that

+4.5 Adding New Enumeration/Discovery Method
+-------------------------------------------
+
+RapidIO subsystem code organization allows addition of new enumeration/discovery
+methods as new configuration options without significant impact to to the core
+RapidIO code.
+
+A new enumeration/discovery method has to be attached to one or more mport
+devices before an enumeration/discovery process can be started. Normally,
+method's module initialization routine calls rio_register_scan() to attach
+an enumerator to a specified mport device (or devices). The basic enumerator

+5. RapidIO Bus Attributes
+-------------------------
+
+RapidIO bus subdirectory /sys/bus/rapidio implements the following bus-specific
+attribute:
+
+ scan - allows to trigger enumeration discovery process from user space. This
+ is a write-only attribute. To initiate an enumeration or discovery
+ process on specific mport device, a user needs to write mport_ID (not
+ RapidIO destination ID) into this file. The mport_ID is a sequential
+ number (0 ... RIO_MAX_MPORTS) assigned to the mport device.
+ For example, for a machine with a single RapidIO controller, mport_ID
+ for that controller always will be 0.
+ To initiate RapidIO enumeration/discovery on all available mports
+ a user must write '-1' (or RIO_MPORT_ANY) into this attribute file.

+ RAMSTER HOW-TO
+
+Author: Dan Magenheimer
+Ramster maintainer: Konrad Wilk <konrad.wilk@oracle.com>
+
+This is a HOWTO document for ramster which, as of this writing, is in
+the kernel as a subdirectory of zcache in drivers/staging, called ramster.
+(Zcache can be built with or without ramster functionality.) If enabled
+and properly configured, ramster allows memory capacity load balancing
+across multiple machines in a cluster. Further, the ramster code serves
+as an example of asynchronous access for zcache (as well as cleancache and
+frontswap) that may prove useful for future transcendent memory
+implementations, such as KVM and NVRAM. While ramster works today on
+any network connection that supports kernel sockets, its features may
+become more interesting on future high-speed fabrics/interconnects.
+
+Ramster requires both kernel and userland support. The userland support,
+called ramster-tools, is known to work with EL6-based distros, but is a
+set of poorly-hacked slightly-modified cluster tools based on ocfs2, which
+includes an init file, a config file, and a userland binary that interfaces
+to the kernel. This state of userland support reflects the abysmal userland
+skills of this suitably-embarrassed author; any help/patches to turn
+ramster-tools into more distributable rpms/debs useful for a wider range
+of distros would be appreciated. The source RPM that can be used as a
+starting point is available at:
+ http://oss.oracle.com/projects/tmem/files/RAMster/
+
+As a result of this author's ignorance, userland setup described in this
+HOWTO assumes an EL6 distro and is described in EL6 syntax. Apologies
+if this offends anyone!
+
+Kernel support has only been tested on x86_64. Systems with an active
+ocfs2 filesystem should work, but since ramster leverages a lot of
+code from ocfs2, there may be latent issues. A kernel configuration that
+includes CONFIG_OCFS2_FS should build OK, and should certainly run OK
+if no ocfs2 filesystem is mounted.
+
+This HOWTO demonstrates memory capacity load balancing for a two-node
+cluster, where one node called the "local" node becomes overcommitted
+and the other node called the "remote" node provides additional RAM
+capacity for use by the local node. Ramster is capable of more complex
+topologies; see the last section titled "ADVANCED RAMSTER TOPOLOGIES".
+
+If you find any terms in this HOWTO unfamiliar or don't understand the
+motivation for ramster, the following LWN reading is recommended:
+-- Transcendent Memory in a Nutshell (lwn.net/Articles/454795)
+-- The future calculus of memory management (lwn.net/Articles/475681)
+And since ramster is built on top of zcache, this article may be helpful:
+-- In-kernel memory compression (lwn.net/Articles/545244)
+
+Now that you've memorized the contents of those articles, let's get started!
+
+A. PRELIMINARY
+
+1) Install two x86_64 Linux systems that are known to work when
+ upgraded to a recent upstream Linux kernel version.
+
+On each system:
+
+2) Configure, build and install, then boot Linux, just to ensure it
+ can be done with an unmodified upstream kernel. Confirm you booted
+ the upstream kernel with "uname -a".
+
+3) If you plan to do any performance testing or unless you plan to
+ test only swapping, the "WasActive" patch is also highly recommended.
+ (Search lkml.org for WasActive, apply the patch, rebuild your kernel.)
+ For a demo or simple testing, the patch can be ignored.
+
+4) Install ramster-tools as root. An x86_64 rpm for EL6-based systems
+ can be found at:
+ http://oss.oracle.com/projects/tmem/files/RAMster/
+ (Sorry but for now, non-EL6 users must recreate ramster-tools on
+ their own from source. See above.)
+
+5) Ensure that debugfs is mounted at each boot. Examples below assume it
+ is mounted at /sys/kernel/debug.
+
+B. BUILDING RAMSTER INTO THE KERNEL
+
+Do the following on each system:
+
+1) Using the kernel configuration mechanism of your choice, change
+ your config to include:
+
+ CONFIG_CLEANCACHE=y
+ CONFIG_FRONTSWAP=y
+ CONFIG_STAGING=y
+ CONFIG_CONFIGFS_FS=y # NOTE: MUST BE y, not m
+ CONFIG_ZCACHE=y
+ CONFIG_RAMSTER=y
+
+ For a linux-3.10 or later kernel, you should also set:
+
+ CONFIG_ZCACHE_DEBUG=y
+ CONFIG_RAMSTER_DEBUG=y
+
+ Before building the kernel please doublecheck your kernel config
+ file to ensure all of the settings are correct.
+
+2) Build this kernel and change your boot file (e.g. /etc/grub.conf)
+ so that the new kernel will boot.
+
+3) Add "zcache" and "ramster" as kernel boot parameters for the new kernel.
+
+4) Reboot each system approximately simultaneously.
+
+5) Check dmesg to ensure there are some messages from ramster, prefixed
+ by "ramster:"
+
+ # dmesg | grep ramster
+
+ You should also see a lot of files in:
+
+ # ls /sys/kernel/debug/zcache
+ # ls /sys/kernel/debug/ramster
+
+ These are mostly counters for various zcache and ramster activities.
+ You should also see files in:
+
+ # ls /sys/kernel/mm/ramster
+
+ These are sysfs files that control ramster as we shall see.
+
+ Ramster now will act as a single-system zcache on each system
+ but doesn't yet know anything about the cluster so can't yet do
+ anything remotely.
+
+C. CONFIGURING THE RAMSTER CLUSTER
+
+This part can be error prone unless you are familiar with clustering
+filesystems. We need to describe the cluster in a /etc/ramster.conf
+file and the init scripts that parse it are extremely picky about
+the syntax.
+
+1) Create a /etc/ramster.conf file and ensure it is identical on both
+ systems. This file mimics the ocfs2 format and there is a good amount
+ of documentation that can be searched for ocfs2.conf, but you can use:
+
+ cluster:
+ name = ramster
+ node_count = 2
+ node:
+ name = system1
+ cluster = ramster
+ number = 0
+ ip_address = my.ip.ad.r1
+ ip_port = 7777
+ node:
+ name = system2
+ cluster = ramster
+ number = 1
+ ip_address = my.ip.ad.r2
+ ip_port = 7777
+
+ You must ensure that the "name" field in the file exactly matches
+ the output of "hostname" on each system; if "hostname" shows a
+ fully-qualified hostname, ensure the name is fully qualified in
+ /etc/ramster.conf. Obviously, substitute my.ip.ad.rx with proper
+ ip addresses.
+
+2) Enable the ramster service and configure it. If you used the
+ EL6 ramster-tools, this would be:
+
+ # chkconfig --add ramster
+ # service ramster configure
+
+ Set "load on boot" to "y", cluster to start is "ramster" (or whatever
+ name you chose in ramster.conf), heartbeat dead threshold as "500",
+ network idle timeout as "1000000". Leave the others as default.
+
+3) Reboot both systems. After reboot, try (assuming EL6 ramster-tools):
+
+ # service ramster status
+
+ You should see "Checking RAMSTER cluster "ramster": Online". If you do
+ not, something is wrong and ramster will not work. Note that you
+ should also see that the driver for "configfs" is loaded and mounted,
+ the driver for ocfs2_dlmfs is not loaded, and some numbers for network
+ parameters. You will also see "Checking RAMSTER heartbeat: Not active".
+ That's all OK.
+
+4) Now you need to start the cluster heartbeat; the cluster is not "up"
+ until all nodes detect a heartbeat. In a real cluster, heartbeat detection
+ is done via a cluster filesystem, but ramster doesn't require one. Some
+ hack-y kernel code in ramster can start the heartbeat for you though if
+ you tell it what nodes are "up". To enable the heartbeat, do:
+
+ # echo 0 > /sys/kernel/mm/ramster/manual_node_up
+ # echo 1 > /sys/kernel/mm/ramster/manual_node_up
+
+ This must be done on BOTH nodes and, to avoid timeouts, must be done
+ approximately concurrently on both nodes. On an EL6 system, it is
+ convenient to put these lines in /etc/rc.local. To confirm that the
+ cluster is now up, on both systems do:
+
+ # dmesg | grep ramster
+
+ You should see ramster "Accepted connection" messages in dmesg on both
+ nodes after this. Note that if you check userland status again with
+
+ # service ramster status
+
+ you will still see "Checking RAMSTER heartbeat: Not active". That's
+ still OK... the ramster kernel heartbeat hack doesn't communicate to
+ userland.
+
+5) You now must tell each node the node to which it should "remotify" pages.
+ On this two node cluster, we will assume the "local" node, node 0, has
+ memory overcommitted and will use ramster to utilize RAM capacity on
+ the "remote node", node 1. To configure this, on node 0, you do:
+
+ # echo 1 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+ You should see "ramster: node 1 set as remotification target" in dmesg
+ on node 0. Again, on EL6, /etc/rc.local is a good place to put this
+ on node 0 so you don't forget to do it at each boot.
+
+6) One more step: By default, the ramster code does not "remotify" any
+ pages; this is primarily for testing purposes, but sometimes it is
+ useful. This may change in the future, but for now, on node 0, you do:
+
+ # echo 1 > /sys/kernel/mm/ramster/pers_remotify_enable
+ # echo 1 > /sys/kernel/mm/ramster/eph_remotify_enable
+
+ The first enables remotifying swap (persistent, aka frontswap) pages,
+ the second enables remotifying of page cache (ephemeral, cleancache)
+ pages.
+
+ On EL6, these lines can also be put in /etc/rc.local (AFTER the
+ node_up lines), or at the beginning of a script that runs a workload.
+
+7) Note that most testing has been done with both/all machines booted
+ roughly simultaneously to avoid cluster timeouts. Ideally, you should
+ do this too unless you are trying to break ramster rather than just
+ use it. ;-)
+
+D. TESTING RAMSTER
+
+1) Note that ramster has no value unless pages get "remotified". For
+ swap/frontswap/persistent pages, this doesn't happen unless/until
+ the workload would cause swapping to occur, at which point pages
+ are put into frontswap/zcache, and the remotification thread starts
+ working. To get to the point where the system swaps, you either
+ need a workload for which the working set exceeds the RAM in the
+ system; or you need to somehow reduce the amount of RAM one of
+ the system sees. This latter is easy when testing in a VM, but
+ harder on physical systems. In some cases, "mem=xxxM" on the
+ kernel command line restricts memory, but for some values of xxx
+ the kernel may fail to boot. One may also try creating a fixed
+ RAMdisk, doing nothing with it, but ensuring that it eats up a fixed
+ amount of RAM.
+
+2) To see if ramster is working, on the "remote node", node 1, try:
+
+ # grep . /sys/kernel/debug/ramster/foreign_*
+ # # note, that is space-dot-space between grep and the pathname
+
+ to monitor the number (and max) ephemeral and persistent pages
+ that ramster has sent. If these stay at zero, ramster is not working
+ either because the workload on the local node (node 0) isn't creating
+ enough memory pressure or because "remotifying" isn't working. On the
+ local system, node 0, you can watch lots of useful information also.
+ Try:
+
+ grep . /sys/kernel/debug/zcache/*pageframes* \
+ /sys/kernel/debug/zcache/*zbytes* \
+ /sys/kernel/debug/zcache/*zpages* \
+ /sys/kernel/debug/ramster/*remote*
+
+ Of particular note are the remote_*_pages_succ_get counters. These
+ show how many disk reads and/or disk writes have been avoided on the
+ overcommitted local system by storing pages remotely using ramster.
+
+ At the risk of information overload, you can also grep:
+
+ /sys/kernel/debug/cleancache/* and /sys/kernel/debug/frontswap/*
+
+ These show, for example, how many disk reads and/or disk writes have
+ been avoided by using zcache to optimize RAM on the local system.
+
+
+AUTOMATIC SWAP REPATRIATION
+
+You may notice that while the systems are idle, the foreign persistent
+page count on the remote machine slowly decreases. This is because
+ramster implements "frontswap selfshrinking": When possible, swap
+pages that have been remotified are slowly repatriated to the local
+machine. This is so that local RAM can be used when possible and
+so that, in case of remote machine crash, the probability of loss
+of data is reduced.
+
+REBOOTING / POWEROFF
+
+If a system is shut down while some of its swap pages still reside
+on a remote system, the system may lock up during the shutdown
+sequence. This will occur if the network is shut down before the
+swap mechansim is shut down, which is the default ordering on many
+distros. To avoid this annoying problem, simply shut off the swap
+subsystem before starting the shutdown sequence, e.g.:
+
+ # swapoff -a
+ # reboot
+
+Ideally, this swapoff-before-ifdown ordering should be enforced permanently
+using shutdown scripts.
+
+KNOWN PROBLEMS
+
+1) You may periodically see messages such as:
+
+ ramster_r2net, message length problem
+
+ This is harmless but indicates that a node is sending messages
+ containing compressed pages that exceed the maximum for zcache
+ (PAGE_SIZE*15/16). The sender side needs to be fixed.
+
+2) If you see a "No longer connected to node..." message or a "No connection
+ established with node X after N seconds", it is possible you may
+ be in an unrecoverable state. If you are certain all of the
+ appropriate cluster configuration steps described above have been
+ performed, try rebooting the two servers concurrently to see if
+ the cluster starts.
+
+ Note that "Connection to node... shutdown, state 7" is an intermediate
+ connection state. As long as you later see "Accepted connection", the
+ intermediate states are harmless.
+
+3) There are known issues in counting certain values. As a result
+ you may see periodic warnings from the kernel. Almost always you
+ will see "ramster: bad accounting for XXX". There are also "WARN_ONCE"
+ messages. If you see kernel warnings with a tombstone, please report
+ them. They are harmless but reflect bugs that need to be eventually fixed.
+
+ADVANCED RAMSTER TOPOLOGIES
+
+The kernel code for ramster can support up to eight nodes in a cluster,
+but no testing has been done with more than three nodes.
+
+In the example described above, the "remote" node serves as a RAM
+overflow for the "local" node. This can be made symmetric by appropriate
+settings of the sysfs remote_target_nodenum file. For example, by setting:
+
+ # echo 1 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 0, and
+
+ # echo 0 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 1, each node can serve as a RAM overflow for the other.
+
+For more than two nodes, a "RAM server" can be configured. For a
+three node system, set:
+
+ # echo 0 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 1, and
+
+ # echo 0 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 2. Then node 0 is a RAM server for node 1 and node 2.
+
+In this implementation of ramster, any remote node is potentially a single
+point of failure (SPOF). Though the probability of failure is reduced
+by automatic swap repatriation (see above), a proposed future enhancement
+to ramster improves high-availability for the cluster by sending a copy
+of each page of date to two other nodes. Patches welcome!

menuconfig USB_PHY
bool "USB Physical Layer drivers"
help
- USB controllers (those which are host, device or DRD) need a
- device to handle the physical layer signalling, commonly called
- a PHY.
+ Most USB controllers have the physical layer signalling part
+ (commonly called a PHY) built in. However, dual-role devices
+ (a.k.a. USB on-the-go) which support being USB master or slave
+ with the same connector often use an external PHY.
- The following drivers add support for such PHY devices.
+ The drivers in this submenu add support for such PHY devices.
+ They are not needed for standard master-only (or the vast
+ majority of slave-only) USB interfaces.
+
+ If you're not sure if this applies to you, it probably doesn't;
+ say N here.

+ * Sort the log items in the transaction.
+ *
+ * The ordering constraints are defined by the inode allocation and unlink
+ * behaviour. The rules are:
+ *
+ * 1. Every item is only logged once in a given transaction. Hence it
+ * represents the last logged state of the item. Hence ordering is
+ * dependent on the order in which operations need to be performed so
+ * required initial conditions are always met.
+ *
+ * 2. Cancelled buffers are recorded in pass 1 in a separate table and
+ * there's nothing to replay from them so we can simply cull them
+ * from the transaction. However, we can't do that until after we've
+ * replayed all the other items because they may be dependent on the
+ * cancelled buffer and replaying the cancelled buffer can remove it
+ * form the cancelled buffer table. Hence they have tobe done last.
+ *
+ * 3. Inode allocation buffers must be replayed before inode items that
+ * read the buffer and replay changes into it.
+ *
+ * 4. Inode unlink buffers must be replayed after inode items are replayed.
+ * This ensures that inodes are completely flushed to the inode buffer
+ * in a "free" state before we remove the unlinked inode list pointer.
+ *
+ * Hence the ordering needs to be inode allocation buffers first, inode items
+ * second, inode unlink buffers third and cancelled buffers last.
+ *
+ * But there's a problem with that - we can't tell an inode allocation buffer
+ * apart from a regular buffer, so we can't separate them. We can, however,
+ * tell an inode unlink buffer from the others, and so we can separate them out
+ * from all the other buffers and move them to last.
+ *
+ * Hence, 4 lists, in order from head to tail:
+ * - buffer_list for all buffers except cancelled/inode unlink buffers
+ * - item_list for all non-buffer items
+ * - inode_buffer_list for inode unlink buffers
+ * - cancel_list for the cancelled buffers

+ - Of course, the expected token list depends on states to have

+ to perform extra reductions after fetching a lookahead from the
+ scanner and before detecting a syntax error. Thus, state merging
+ (from LALR or IELR) and default reductions corrupt the expected
