2 tristate "Reiserfs support"
5 Stores not just filenames but the files themselves in a balanced
6 tree. Uses journalling.
8 Balanced trees are more efficient than traditional file system
9 architectural foundations.
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.
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.
31 bool "Enable reiserfs debug mode"
32 depends on REISERFS_FS
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.
44 config REISERFS_PROC_INFO
45 bool "Stats in /proc/fs/reiserfs"
46 depends on REISERFS_FS && PROC_FS
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.
55 config REISERFS_FS_XATTR
56 bool "ReiserFS extended attributes"
57 depends on REISERFS_FS
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).
64 config REISERFS_FS_POSIX_ACL
65 bool "ReiserFS POSIX Access Control Lists"
66 depends on REISERFS_FS_XATTR
69 Posix Access Control Lists (ACLs) support permissions for users and
70 groups beyond the owner/group/world scheme.
72 If you don't know what Access Control Lists are, say N
74 config REISERFS_FS_SECURITY
75 bool "ReiserFS Security Labels"
76 depends on REISERFS_FS_XATTR
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.
83 If you are not using a security module that requires using
84 extended attributes for file security labels, say N.
