1config REISERFS_FS
2	tristate "Reiserfs support"
3	select CRC32
4	help
5	  Stores not just filenames but the files themselves in a balanced
6	  tree.  Uses journalling.
7
8	  Balanced trees are more efficient than traditional file system
9	  architectural foundations.
10
11	  In general, ReiserFS is as fast as ext2, but is very efficient with
12	  large directories and small files.  Additional patches are needed
13	  for NFS and quotas, please see
14	  <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.
15
16	  It is more easily extended to have features currently found in
17	  database and keyword search systems than block allocation based file
18	  systems are.  The next version will be so extended, and will support
19	  plugins consistent with our motto ``It takes more than a license to
20	  make source code open.''

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

30config REISERFS_CHECK
31	bool "Enable reiserfs debug mode"
32	depends on REISERFS_FS
33	help
34	  If you set this to Y, then ReiserFS will perform every check it can
35	  possibly imagine of its internal consistency throughout its
36	  operation.  It will also go substantially slower.  More than once we
37	  have forgotten that this was on, and then gone despondent over the
38	  latest benchmarks.:-) Use of this option allows our team to go all
39	  out in checking for consistency when debugging without fear of its
40	  effect on end users.  If you are on the verge of sending in a bug
41	  report, say Y and you might get a useful error message.  Almost
42	  everyone should say N.
43
44config REISERFS_PROC_INFO
45	bool "Stats in /proc/fs/reiserfs"
46	depends on REISERFS_FS && PROC_FS
47	help
48	  Create under /proc/fs/reiserfs a hierarchy of files, displaying
49	  various ReiserFS statistics and internal data at the expense of
50	  making your kernel or module slightly larger (+8 KB). This also
51	  increases the amount of kernel memory required for each mount.
52	  Almost everyone but ReiserFS developers and people fine-tuning
53	  reiserfs or tracing problems should say N.
54
55config REISERFS_FS_XATTR
56	bool "ReiserFS extended attributes"
57	depends on REISERFS_FS
58	help
59	  Extended attributes are name:value pairs associated with inodes by
60	  the kernel or by users (see the attr(5) manual page for details).
61
62	  If unsure, say N.
63
64config REISERFS_FS_POSIX_ACL
65	bool "ReiserFS POSIX Access Control Lists"
66	depends on REISERFS_FS_XATTR
67	select FS_POSIX_ACL
68	help
69	  Posix Access Control Lists (ACLs) support permissions for users and
70	  groups beyond the owner/group/world scheme.
71
72	  If you don't know what Access Control Lists are, say N
73
74config REISERFS_FS_SECURITY
75	bool "ReiserFS Security Labels"
76	depends on REISERFS_FS_XATTR
77	help
78	  Security labels support alternative access control models
79	  implemented by security modules like SELinux.  This option
80	  enables an extended attribute handler for file security
81	  labels in the ReiserFS filesystem.
82
83	  If you are not using a security module that requires using
84	  extended attributes for file security labels, say N.
