5 Stores not just filenames but the files themselves in a balanced
6 tree. Uses journalling.
7
8 Balanced trees are more efficient than traditional file system
9 architectural foundations.
10
11 In general, ReiserFS is as fast as ext2, but is very efficient with
12 large directories and small files. Additional patches are needed
13 for NFS and quotas, please see <http://www.namesys.com/> for links.
14
15 It is more easily extended to have features currently found in
16 database and keyword search systems than block allocation based file
17 systems are. The next version will be so extended, and will support
18 plugins consistent with our motto ``It takes more than a license to
19 make source code open.''

25 If you like it, you can pay us to add new features to it that you
26 need, buy a support contract, or pay us to port it to another OS.

28config REISERFS_CHECK
29 bool "Enable reiserfs debug mode"
30 depends on REISERFS_FS
31 help
32 If you set this to Y, then ReiserFS will perform every check it can
33 possibly imagine of its internal consistency throughout its
34 operation. It will also go substantially slower. More than once we
35 have forgotten that this was on, and then gone despondent over the
36 latest benchmarks.:-) Use of this option allows our team to go all
37 out in checking for consistency when debugging without fear of its
38 effect on end users. If you are on the verge of sending in a bug
39 report, say Y and you might get a useful error message. Almost
40 everyone should say N.
41
42config REISERFS_PROC_INFO
43 bool "Stats in /proc/fs/reiserfs"
44 depends on REISERFS_FS && PROC_FS
45 help
46 Create under /proc/fs/reiserfs a hierarchy of files, displaying
47 various ReiserFS statistics and internal data at the expense of
48 making your kernel or module slightly larger (+8 KB). This also
49 increases the amount of kernel memory required for each mount.
50 Almost everyone but ReiserFS developers and people fine-tuning
51 reiserfs or tracing problems should say N.
52
53config REISERFS_FS_XATTR
54 bool "ReiserFS extended attributes"
55 depends on REISERFS_FS
56 help
57 Extended attributes are name:value pairs associated with inodes by
58 the kernel or by users (see the attr(5) manual page, or visit
59 <http://acl.bestbits.at/> for details).
60
61 If unsure, say N.

63config REISERFS_FS_POSIX_ACL
64 bool "ReiserFS POSIX Access Control Lists"
65 depends on REISERFS_FS_XATTR
66 select FS_POSIX_ACL
67 help
68 Posix Access Control Lists (ACLs) support permissions for users and
69 groups beyond the owner/group/world scheme.
70
71 To learn more about Access Control Lists, visit the Posix ACLs for
72 Linux website <http://acl.bestbits.at/>.
73
74 If you don't know what Access Control Lists are, say N
75
76config REISERFS_FS_SECURITY
77 bool "ReiserFS Security Labels"
78 depends on REISERFS_FS_XATTR
79 help
80 Security labels support alternative access control models
81 implemented by security modules like SELinux. This option
82 enables an extended attribute handler for file security
83 labels in the ReiserFS filesystem.
84
85 If you are not using a security module that requires using
86 extended attributes for file security labels, say N.
