3 tristate "Reiserfs support (deprecated)"
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.
10 Reiserfs stores not just filenames but the files themselves in a
11 balanced tree. Uses journalling.
13 Balanced trees are more efficient than traditional file system
14 architectural foundations.
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.
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.''

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.
36 bool "Enable reiserfs debug mode"
37 depends on REISERFS_FS
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.
49 config REISERFS_PROC_INFO
50 bool "Stats in /proc/fs/reiserfs"
51 depends on REISERFS_FS && PROC_FS
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.
60 config REISERFS_FS_XATTR
61 bool "ReiserFS extended attributes"
62 depends on REISERFS_FS
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).
69 config REISERFS_FS_POSIX_ACL
70 bool "ReiserFS POSIX Access Control Lists"
71 depends on REISERFS_FS_XATTR
74 Posix Access Control Lists (ACLs) support permissions for users and
75 groups beyond the owner/group/world scheme.
77 If you don't know what Access Control Lists are, say N
79 config REISERFS_FS_SECURITY
80 bool "ReiserFS Security Labels"
81 depends on REISERFS_FS_XATTR
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.
88 If you are not using a security module that requires using
89 extended attributes for file security labels, say N.
