2config REISERFS_FS
3	tristate "Reiserfs support"
4	select CRC32
5	help
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
14	  for NFS and quotas, please see
15	  <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.
16
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.''

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

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.
44
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
61	  the kernel or by users (see the attr(5) manual page 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	  If you don't know what Access Control Lists are, say N
74
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.
