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

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

27config REISERFS_CHECK
28 bool "Enable reiserfs debug mode"
29 depends on REISERFS_FS
30 help
31 If you set this to Y, then ReiserFS will perform every check it can
32 possibly imagine of its internal consistency throughout its
33 operation. It will also go substantially slower. More than once we
34 have forgotten that this was on, and then gone despondent over the
35 latest benchmarks.:-) Use of this option allows our team to go all
36 out in checking for consistency when debugging without fear of its
37 effect on end users. If you are on the verge of sending in a bug
38 report, say Y and you might get a useful error message. Almost
39 everyone should say N.

41config REISERFS_PROC_INFO
42 bool "Stats in /proc/fs/reiserfs"
43 depends on REISERFS_FS && PROC_FS
44 help
45 Create under /proc/fs/reiserfs a hierarchy of files, displaying
46 various ReiserFS statistics and internal data at the expense of
47 making your kernel or module slightly larger (+8 KB). This also
48 increases the amount of kernel memory required for each mount.
49 Almost everyone but ReiserFS developers and people fine-tuning
50 reiserfs or tracing problems should say N.
51
52config REISERFS_FS_XATTR
53 bool "ReiserFS extended attributes"
54 depends on REISERFS_FS
55 help
56 Extended attributes are name:value pairs associated with inodes by
57 the kernel or by users (see the attr(5) manual page, or visit
58 <http://acl.bestbits.at/> for details).
59
60 If unsure, say N.
61
62config REISERFS_FS_POSIX_ACL
63 bool "ReiserFS POSIX Access Control Lists"
64 depends on REISERFS_FS_XATTR
65 select FS_POSIX_ACL
66 help
67 Posix Access Control Lists (ACLs) support permissions for users and
68 groups beyond the owner/group/world scheme.
69
70 To learn more about Access Control Lists, visit the Posix ACLs for
71 Linux website <http://acl.bestbits.at/>.
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.
