Yeah, sometimes I can not reply immediately..

Ok, let's start with #14
Since google dropped the cache, pull it as the first item of this list:
http://lkml.org/lkml/2006/8/3/38 (about set_page_dirty_internal).

Also there is a small, but nasty leak of free disk space when process
runs in
no-space-left-on-device mode. It can be reproduced by the following way:

1) format a small partition by mkfs.reiser4 with no options;
2) mount it and look at "df" output;
3) run stress.sh -n 20; let it to work some time with complaints about
no space left on device;
4) terminate stress benchmark and remove everything on the partition;
5) sync and look at "df" output: it can show more used space, then it
was reported at (2).

It would be great to fix this leak.
There is a hint: this leak is related to tail conversion (if you format
a partition with "extents only" policy, then it doesn't take place).

Thanks,
Edward.
