7	  Reiserfs is deprecated and scheduled to be removed from the kernel
8	  in 2025. If you are still using it, please migrate to another
9	  filesystem or tell us your usecase for reiserfs.
10
11	  Reiserfs stores not just filenames but the files themselves in a
12	  balanced tree.  Uses journalling.
13
14	  Balanced trees are more efficient than traditional file system
15	  architectural foundations.
16
17	  In general, ReiserFS is as fast as ext2, but is very efficient with
18	  large directories and small files.  Additional patches are needed
19	  for NFS and quotas, please see
20	  <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.
21
22	  It is more easily extended to have features currently found in
23	  database and keyword search systems than block allocation based file
24	  systems are.  The next version will be so extended, and will support
25	  plugins consistent with our motto ``It takes more than a license to
26	  make source code open.''

28	  Read <https://reiser4.wiki.kernel.org/index.php/Main_Page>
29	  to learn more about reiserfs.

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

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