+Reiser4 filesystem
+==================
+Reiser4 is a file system based on dancing tree algorithms, and is
+described at
http://www.namesys.com
+
+
+References
+==========
+web page
http://namesys.com/v4/v4.html
+source code and
+userland tools
http://thebsh.namesys.com/snapshots/LATEST
+
+
+Compile options
+===============
+Enable reiser4 debug mode
+ This checks everything imaginable while reiser4
+ runs
+
+Mount options
+=============
+tmgr.atom_max_size=N
+ Atoms containing more than N blocks will be forced to commit.
+ N is decimal.
+ Default is nr_free_pagecache_pages() / 2 at mount time.
+
+tmgr.atom_max_age=N
+ Atoms older than N seconds will be forced to commit. N is decimal.
+ Default is 600.
+
+tmgr.atom_max_flushers=N
+ Limit of concurrent flushers for one atom. 0 means no limit.
+ Default is 0.
+
+tree.cbk_cache.nr_slots=N
+ Number of slots in the cbk cache.
+
+flush.relocate_threshold=N
+ If flush finds more than N adjacent dirty leaf-level blocks it
+ will force them to be relocated.
+ Default is 64.
+
+flush.relocate_distance=N
+ If flush finds can find a block allocation closer than at most
+ N from the preceder it will relocate to that position.
+ Default is 64.
+
+flush.scan_maxnodes=N
+ The maximum number of nodes to scan left on a level during
+ flush.
+ Default is 10000.
+
+optimal_io_size=N
+ Preferred IO size. This value is used to set st_blksize of
+ struct stat.
+ Default is 65536.
+
+bsdgroups
+ Turn on BSD-style gid assignment.
+
+32bittimes
+ By default file in reiser4 have 64 bit timestamps. Files
+ created when filesystem is mounted with 32bittimes mount
+ option will get 32 bit timestamps.
+
+mtflush
+ Turn off concurrent flushing.
+
+nopseudo
+ Disable pseudo files support. See
+
http://namesys.com/v4/pseudo.html for more about pseudo files.
+
+dont_load_bitmap
+ Don't load all bitmap blocks at mount time, it is useful for
+ machines with tiny RAM and large disks.
