Subject: [GIT PULL] SLUB updates for 2.6.27

Hi Linus,

Please pull the latest SLAB git tree from:

  git://git.kernel.org/pub/scm/linux/kernel/git/penberg/slab-2.6.git for-linus

The tree has one cleanup patch from Alexey and a small fix for SLUB debugging
by me.

I am heading off to OLS (as apprently is Christoph) so expect some downtime
from us SLUB folks this week. In case anyone is wondering, the SLUB defrag
patches have been postponed to 2.6.28 due to lack of time from Christoph.

                Pekka

Alexey Dobriyan (1):
      SLUB: simplify re on_each_cpu()

Pekka Enberg (1):
      slub: dump more data on slab corruption
