3 tristate "Reiserfs support (deprecated)"
5 select LEGACY_DIRECT_IO
7 Reiserfs is deprecated and scheduled to be removed from the kernel
8 in 2025. If you are still using it, please migrate to another
9 filesystem or tell us your usecase for reiserfs.
11 Reiserfs stores not just filenames but the files themselves in a
12 balanced tree. Uses journalling.
14 Balanced trees are more efficient than traditional file system
15 architectural foundations.
17 In general, ReiserFS is as fast as ext2, but is very efficient with
18 large directories and small files. Additional patches are needed
19 for NFS and quotas, please see
20 <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.
22 It is more easily extended to have features currently found in
23 database and keyword search systems than block allocation based file
24 systems are. The next version will be so extended, and will support
25 plugins consistent with our motto ``It takes more than a license to
26 make source code open.''

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