4	select CRC32
5	help
6	  Reiserfs is deprecated and scheduled to be removed from the kernel
7	  in 2025. If you are still using it, please migrate to another
8	  filesystem or tell us your usecase for reiserfs.
9
10	  Reiserfs stores not just filenames but the files themselves in a
11	  balanced tree.  Uses journalling.
12
13	  Balanced trees are more efficient than traditional file system
14	  architectural foundations.
15
16	  In general, ReiserFS is as fast as ext2, but is very efficient with
17	  large directories and small files.  Additional patches are needed
18	  for NFS and quotas, please see
19	  <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.
20
21	  It is more easily extended to have features currently found in
22	  database and keyword search systems than block allocation based file
23	  systems are.  The next version will be so extended, and will support
24	  plugins consistent with our motto ``It takes more than a license to
25	  make source code open.''
26
27	  Read <https://reiser4.wiki.kernel.org/index.php/Main_Page>
28	  to learn more about reiserfs.

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

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