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

 29           Read <https://reiser4.wiki.kernel.org/index.php/Main_Page>

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

 37 config REISERFS_CHECK
 38         bool "Enable reiserfs debug mode"
 39         depends on REISERFS_FS
 40         help
 41           If you set this to Y, then ReiserFS will perform every check it can
 42           possibly imagine of its internal consistency throughout its
 43           operation.  It will also go substantially slower.  More than once we
 44           have forgotten that this was on, and then gone despondent over the
 45           latest benchmarks.:-) Use of this option allows our team to go all
 46           out in checking for consistency when debugging without fear of its
 47           effect on end users.  If you are on the verge of sending in a bug
 48           report, say Y and you might get a useful error message.  Almost
 49           everyone should say N.
 50 
 51 config REISERFS_PROC_INFO
 52         bool "Stats in /proc/fs/reiserfs"
 53         depends on REISERFS_FS && PROC_FS
 54         help
 55           Create under /proc/fs/reiserfs a hierarchy of files, displaying
 56           various ReiserFS statistics and internal data at the expense of
 57           making your kernel or module slightly larger (+8 KB). This also
 58           increases the amount of kernel memory required for each mount.
 59           Almost everyone but ReiserFS developers and people fine-tuning
 60           reiserfs or tracing problems should say N.
 61 
 62 config REISERFS_FS_XATTR
 63         bool "ReiserFS extended attributes"
 64         depends on REISERFS_FS
 65         help
 66           Extended attributes are name:value pairs associated with inodes by
 67           the kernel or by users (see the attr(5) manual page for details).
 68 
 69           If unsure, say N.
 70 
 71 config REISERFS_FS_POSIX_ACL
 72         bool "ReiserFS POSIX Access Control Lists"
 73         depends on REISERFS_FS_XATTR
 74         select FS_POSIX_ACL
 75         help
 76           Posix Access Control Lists (ACLs) support permissions for users and
 77           groups beyond the owner/group/world scheme.
 78 
 79           If you don't know what Access Control Lists are, say N
 80 
 81 config REISERFS_FS_SECURITY
 82         bool "ReiserFS Security Labels"
 83         depends on REISERFS_FS_XATTR
 84         help
 85           Security labels support alternative access control models
 86           implemented by security modules like SELinux.  This option
 87           enables an extended attribute handler for file security
 88           labels in the ReiserFS filesystem.
 89 
 90           If you are not using a security module that requires using
 91           extended attributes for file security labels, say N.
