8	  Reiserfs is deprecated and scheduled to be removed from the kernel
9	  in 2025. If you are still using it, please migrate to another
10	  filesystem or tell us your usecase for reiserfs.
11
12	  Reiserfs stores not just filenames but the files themselves in a
13	  balanced tree.  Uses journalling.
14
15	  Balanced trees are more efficient than traditional file system
16	  architectural foundations.
17
18	  In general, ReiserFS is as fast as ext2, but is very efficient with
19	  large directories and small files.  Additional patches are needed
20	  for NFS and quotas, please see
21	  <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.
22
23	  It is more easily extended to have features currently found in
24	  database and keyword search systems than block allocation based file
25	  systems are.  The next version will be so extended, and will support
26	  plugins consistent with our motto ``It takes more than a license to
27	  make source code open.''
28
29	  Read <https://reiser4.wiki.kernel.org/index.php/Main_Page>
30	  to learn more about reiserfs.

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

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

51config REISERFS_PROC_INFO
52	bool "Stats in /proc/fs/reiserfs"
53	depends on REISERFS_FS && PROC_FS
54	help
55	  Create under /proc/fs/reiserfs a hierarchy of files, displaying
56	  various ReiserFS statistics and internal data at the expense of
57	  making your kernel or module slightly larger (+8 KB). This also
58	  increases the amount of kernel memory required for each mount.
59	  Almost everyone but ReiserFS developers and people fine-tuning
60	  reiserfs or tracing problems should say N.
61
62config REISERFS_FS_XATTR
63	bool "ReiserFS extended attributes"
64	depends on REISERFS_FS
65	help
66	  Extended attributes are name:value pairs associated with inodes by
67	  the kernel or by users (see the attr(5) manual page for details).
68
69	  If unsure, say N.

71config REISERFS_FS_POSIX_ACL
72	bool "ReiserFS POSIX Access Control Lists"
73	depends on REISERFS_FS_XATTR
74	select FS_POSIX_ACL
75	help
76	  Posix Access Control Lists (ACLs) support permissions for users and
77	  groups beyond the owner/group/world scheme.
78
79	  If you don't know what Access Control Lists are, say N
80
81config REISERFS_FS_SECURITY
82	bool "ReiserFS Security Labels"
83	depends on REISERFS_FS_XATTR
84	help
85	  Security labels support alternative access control models
86	  implemented by security modules like SELinux.  This option
87	  enables an extended attribute handler for file security
88	  labels in the ReiserFS filesystem.
89
90	  If you are not using a security module that requires using
91	  extended attributes for file security labels, say N.
