   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.

  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

  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.

  44 config REISERFS_PROC_INFO
  45         bool "Stats in /proc/fs/reiserfs"

  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.

  66         bool "ReiserFS POSIX Access Control Lists"

  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/>.

  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.
