  5           Stores not just filenames but the files themselves in a balanced
  6           tree.  Uses journalling.
  7 
  8           Balanced trees are more efficient than traditional file system
  9           architectural foundations.
 10 
 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.
 15 
 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.

 30 config REISERFS_CHECK
 31         bool "Enable reiserfs debug mode"
 32         depends on REISERFS_FS
 33         help
 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.
 43 
 44 config REISERFS_PROC_INFO
 45         bool "Stats in /proc/fs/reiserfs"

 47         help
 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.
 54 
 55 config REISERFS_FS_XATTR
 56         bool "ReiserFS extended attributes"
 57         depends on REISERFS_FS
 58         help
 59           Extended attributes are name:value pairs associated with inodes by
 60           the kernel or by users (see the attr(5) manual page, or visit
 61           <http://acl.bestbits.at/> for details).
 62 
 63           If unsure, say N.
 64 
 65 config REISERFS_FS_POSIX_ACL
 66         bool "ReiserFS POSIX Access Control Lists"
 67         depends on REISERFS_FS_XATTR
 68         select FS_POSIX_ACL
 69         help
 70           Posix Access Control Lists (ACLs) support permissions for users and
 71           groups beyond the owner/group/world scheme.
 72 
 73           To learn more about Access Control Lists, visit the Posix ACLs for
 74           Linux website <http://acl.bestbits.at/>.
 75 
 76           If you don't know what Access Control Lists are, say N
 77 
 78 config REISERFS_FS_SECURITY
 79         bool "ReiserFS Security Labels"
 80         depends on REISERFS_FS_XATTR
 81         help
 82           Security labels support alternative access control models
 83           implemented by security modules like SELinux.  This option
 84           enables an extended attribute handler for file security
 85           labels in the ReiserFS filesystem.
 86 
 87           If you are not using a security module that requires using
 88           extended attributes for file security labels, say N.
