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

16 It is more easily extended to have features currently found in
17 database and keyword search systems than block allocation based file
18 systems are. The next version will be so extended, and will support
19 plugins consistent with our motto ``It takes more than a license to
20 make source code open.''

30config REISERFS_CHECK
31 bool "Enable reiserfs debug mode"
32 depends on REISERFS_FS
33 help
34 If you set this to Y, then ReiserFS will perform every check it can
35 possibly imagine of its internal consistency throughout its
36 operation. It will also go substantially slower. More than once we
37 have forgotten that this was on, and then gone despondent over the
38 latest benchmarks.:-) Use of this option allows our team to go all
39 out in checking for consistency when debugging without fear of its
40 effect on end users. If you are on the verge of sending in a bug
41 report, say Y and you might get a useful error message. Almost
42 everyone should say N.
43
44config REISERFS_PROC_INFO
45 bool "Stats in /proc/fs/reiserfs"
46 depends on REISERFS_FS && PROC_FS
47 help
48 Create under /proc/fs/reiserfs a hierarchy of files, displaying
49 various ReiserFS statistics and internal data at the expense of
50 making your kernel or module slightly larger (+8 KB). This also
51 increases the amount of kernel memory required for each mount.
52 Almost everyone but ReiserFS developers and people fine-tuning
53 reiserfs or tracing problems should say N.
54
55config REISERFS_FS_XATTR
56 bool "ReiserFS extended attributes"
57 depends on REISERFS_FS
58 help
59 Extended attributes are name:value pairs associated with inodes by
60 the kernel or by users (see the attr(5) manual page, or visit
61 <http://acl.bestbits.at/> for details).
62
63 If unsure, say N.
64
65config REISERFS_FS_POSIX_ACL
66 bool "ReiserFS POSIX Access Control Lists"
67 depends on REISERFS_FS_XATTR
68 select FS_POSIX_ACL
69 help
70 Posix Access Control Lists (ACLs) support permissions for users and
71 groups beyond the owner/group/world scheme.
72
73 To learn more about Access Control Lists, visit the Posix ACLs for
74 Linux website <http://acl.bestbits.at/>.
75
76 If you don't know what Access Control Lists are, say N
77
78config REISERFS_FS_SECURITY
79 bool "ReiserFS Security Labels"
80 depends on REISERFS_FS_XATTR
81 help
82 Security labels support alternative access control models
83 implemented by security modules like SELinux. This option
84 enables an extended attribute handler for file security
85 labels in the ReiserFS filesystem.
86
87 If you are not using a security module that requires using
88 extended attributes for file security labels, say N.
