Re: reiser4 bug with firefox on kernels 2.6.36 and 2.6.39

[Edward Shishkin <edward.shishkin@gmail.com>]

This is an old problem with unexpected fragmentation, when
all reserved blocks are exhausted. There is a dirty fixup
you can apply as a temporal solution:

http://marc.info/?l=reiserfs-devel&m=129721907717548&q=p3

Note that this fixup can cause unexpected no-space-on-device
when a lot of parallel processes do something with reiser4.

Edward.

P.S. Cut the part of this patch which produces flooding
warnings with "2222"..
