6 Stores not just filenames but the files themselves in a balanced
7 tree. Uses journalling.
8
9 Balanced trees are more efficient than traditional file system
10 architectural foundations.
11
12 In general, ReiserFS is as fast as ext2, but is very efficient with
13 large directories and small files. Additional patches are needed

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

31config REISERFS_CHECK
32 bool "Enable reiserfs debug mode"
33 depends on REISERFS_FS
34 help
35 If you set this to Y, then ReiserFS will perform every check it can
36 possibly imagine of its internal consistency throughout its
37 operation. It will also go substantially slower. More than once we
38 have forgotten that this was on, and then gone despondent over the
39 latest benchmarks.:-) Use of this option allows our team to go all
40 out in checking for consistency when debugging without fear of its
41 effect on end users. If you are on the verge of sending in a bug
42 report, say Y and you might get a useful error message. Almost
43 everyone should say N.

45config REISERFS_PROC_INFO
46 bool "Stats in /proc/fs/reiserfs"
47 depends on REISERFS_FS && PROC_FS
48 help
49 Create under /proc/fs/reiserfs a hierarchy of files, displaying
50 various ReiserFS statistics and internal data at the expense of
51 making your kernel or module slightly larger (+8 KB). This also
52 increases the amount of kernel memory required for each mount.
53 Almost everyone but ReiserFS developers and people fine-tuning
54 reiserfs or tracing problems should say N.
55
56config REISERFS_FS_XATTR
57 bool "ReiserFS extended attributes"
58 depends on REISERFS_FS
59 help
60 Extended attributes are name:value pairs associated with inodes by
Adam Borowski91581e42017-12-20 14:58:52 +010061 the kernel or by users (see the attr(5) manual page for details).
Alexey Dobriyanb16ecfe2009-01-22 10:22:31 +030062

70 Posix Access Control Lists (ACLs) support permissions for users and
71 groups beyond the owner/group/world scheme.
72
Alexey Dobriyanb16ecfe2009-01-22 10:22:31 +030073 If you don't know what Access Control Lists are, say N

75config REISERFS_FS_SECURITY
76 bool "ReiserFS Security Labels"
77 depends on REISERFS_FS_XATTR
78 help
79 Security labels support alternative access control models
80 implemented by security modules like SELinux. This option
81 enables an extended attribute handler for file security
82 labels in the ReiserFS filesystem.
83
84 If you are not using a security module that requires using
85 extended attributes for file security labels, say N.
