[ANNOUNCE]: reiser4

[Nikita Danilov]

Hello,

Snapshot of reiser4 source code can be found at 
http://www.namesys.com/snapshots/2002.10.29/.

It is set of patches against current Linus BK tree (2.5.44).

Reiser4 is the next version of ReiserFS file system. It was re-written
from the scratch. It supports:

 - full data journalling with "wandered logs" ("shadows" in DB
   parlance);

 - extent-based files;

 - delayed allocation of disk space and on-line optimization of disk
   layout across file boundaries;

 - plugins: infrastructure for easy extention of file system and utils
   functionality;

 - and a lot more, see http://www.namesys.com/v4/v4.html

Snapshot contains reiser4 proper (fs_reiser4.diff), set of patches
(described in READ.ME) with necessary changes to the core kernel, and
utils package (in particlar, mkfs.reiser4).

It is still crasheable. Do not put critical data on it.

Nikita.

The current Linus BK tree is quite a bit different from 2.5.44 ;-)

Take a look at 2.5.44-bk1 at 
ftp://ftp.kernel.org/pub/linux/kernel/v2.5/snapshots/

A -bk2 snapshot should appear within the hour, too, with heaps of 
additional changes.

Sorry, my fault.

Patches in reiser4 snapshot are against Linus BK repository at
http://linux.bkbits.net/linux-2.5. Numbers 2, 5, and 44, are, of course,
just VERSION, PATCHLEVEL, and SUBLEVEL in the Makefile of the said
repository.

Probably we should prepare patches against ftp.kernel.org shapshots
instead.

The following is needed to compile reiser4 in 2.5.44-bk3:
