5b16ecfe2SAlexey Dobriyan	  Stores not just filenames but the files themselves in a balanced
6b16ecfe2SAlexey Dobriyan	  tree.  Uses journalling.
7b16ecfe2SAlexey Dobriyan
8b16ecfe2SAlexey Dobriyan	  Balanced trees are more efficient than traditional file system
9b16ecfe2SAlexey Dobriyan	  architectural foundations.
10b16ecfe2SAlexey Dobriyan
11b16ecfe2SAlexey Dobriyan	  In general, ReiserFS is as fast as ext2, but is very efficient with
12b16ecfe2SAlexey Dobriyan	  large directories and small files.  Additional patches are needed
13631dd1a8SJustin P. Mattock	  for NFS and quotas, please see
14631dd1a8SJustin P. Mattock	  <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.
15b16ecfe2SAlexey Dobriyan
16b16ecfe2SAlexey Dobriyan	  It is more easily extended to have features currently found in
17b16ecfe2SAlexey Dobriyan	  database and keyword search systems than block allocation based file
18b16ecfe2SAlexey Dobriyan	  systems are.  The next version will be so extended, and will support
19b16ecfe2SAlexey Dobriyan	  plugins consistent with our motto ``It takes more than a license to
20b16ecfe2SAlexey Dobriyan	  make source code open.''

33b16ecfe2SAlexey Dobriyan	help
34b16ecfe2SAlexey Dobriyan	  If you set this to Y, then ReiserFS will perform every check it can
35b16ecfe2SAlexey Dobriyan	  possibly imagine of its internal consistency throughout its
36b16ecfe2SAlexey Dobriyan	  operation.  It will also go substantially slower.  More than once we
37b16ecfe2SAlexey Dobriyan	  have forgotten that this was on, and then gone despondent over the
38b16ecfe2SAlexey Dobriyan	  latest benchmarks.:-) Use of this option allows our team to go all
39b16ecfe2SAlexey Dobriyan	  out in checking for consistency when debugging without fear of its
40b16ecfe2SAlexey Dobriyan	  effect on end users.  If you are on the verge of sending in a bug
41b16ecfe2SAlexey Dobriyan	  report, say Y and you might get a useful error message.  Almost
42b16ecfe2SAlexey Dobriyan	  everyone should say N.

48b16ecfe2SAlexey Dobriyan	  Create under /proc/fs/reiserfs a hierarchy of files, displaying
49b16ecfe2SAlexey Dobriyan	  various ReiserFS statistics and internal data at the expense of
50b16ecfe2SAlexey Dobriyan	  making your kernel or module slightly larger (+8 KB). This also
51b16ecfe2SAlexey Dobriyan	  increases the amount of kernel memory required for each mount.
52b16ecfe2SAlexey Dobriyan	  Almost everyone but ReiserFS developers and people fine-tuning
53b16ecfe2SAlexey Dobriyan	  reiserfs or tracing problems should say N.

59b16ecfe2SAlexey Dobriyan	  Extended attributes are name:value pairs associated with inodes by

77b16ecfe2SAlexey Dobriyan	help
78b16ecfe2SAlexey Dobriyan	  Security labels support alternative access control models
79b16ecfe2SAlexey Dobriyan	  implemented by security modules like SELinux.  This option
80b16ecfe2SAlexey Dobriyan	  enables an extended attribute handler for file security
