Hi Linus,

Please pull the latest SLUB git tree from:

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

It contains two minor fixes that improve SLUB debugging support.

                Pekka

Christoph Lameter (1):
      slub: fix parameters passed to slab_bug()

Pekka Enberg (1):
      slub: improve kmem_cache_destroy() error message
