v2.6.38-6555-ga44f99c: null pointer dereference on -ENOSPC

[Sergei Trofimovich <slyich@gmail.com>]

[-- Attachment #1.1: Type: text/plain, Size: 4705 bytes --]

The partition is a physical ~5GB --mixed lzo compressed partition.

I run large compiles there. During one of those kernel OOpsed
(It seems to be reproducible). At the time of OOps and after reboot 'du -hs'
reports 2.5GBs free. Before compiation 'du -hs' reported 3.4GBs free.

kernel version: v2.6.38-6555-ga44f99c (a bit outdated linus's master branch)

OOps snippet:
