   6           Stores not just filenames but the files themselves in a balanced
   7           tree.  Uses journalling.
   8
   9           Balanced trees are more efficient than traditional file system
  10           architectural foundations.
  11
  12           In general, ReiserFS is as fast as ext2, but is very efficient with
  13           large directories and small files.  Additional patches are needed
  14           for NFS and quotas, please see
  15           <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.

  17           It is more easily extended to have features currently found in
  18           database and keyword search systems than block allocation based file
  19           systems are.  The next version will be so extended, and will support
  20           plugins consistent with our motto ``It takes more than a license to
  21           make source code open.''

  35           If you set this to Y, then ReiserFS will perform every check it can
  36           possibly imagine of its internal consistency throughout its
  37           operation.  It will also go substantially slower.  More than once we
  38           have forgotten that this was on, and then gone despondent over the
  39           latest benchmarks.:-) Use of this option allows our team to go all
  40           out in checking for consistency when debugging without fear of its
  41           effect on end users.  If you are on the verge of sending in a bug
  42           report, say Y and you might get a useful error message.  Almost
  43           everyone should say N.

  49           Create under /proc/fs/reiserfs a hierarchy of files, displaying
  50           various ReiserFS statistics and internal data at the expense of
  51           making your kernel or module slightly larger (+8 KB). This also
  52           increases the amount of kernel memory required for each mount.
  53           Almost everyone but ReiserFS developers and people fine-tuning
  54           reiserfs or tracing problems should say N.

  60           Extended attributes are name:value pairs associated with inodes by
  61           the kernel or by users (see the attr(5) manual page for details).

  79           Security labels support alternative access control models
  80           implemented by security modules like SELinux.  This option
  81           enables an extended attribute handler for file security
  82           labels in the ReiserFS filesystem.
  83
  84           If you are not using a security module that requires using
  85           extended attributes for file security labels, say N.
