[GIT PULL] SLAB/SLUB fixes for 2.6.29-rc3

[Pekka J Enberg]

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 branch has a build failure fix for SLAB by Jeff Mahoney and a small 
off-by-one fixlet for SLUB by David Rientjes.

                Pekka

David Rientjes (1):
      slub: fix per cpu kmem_cache_cpu array memory leak

Jeff Mahoney (1):
      kmalloc: return NULL instead of link failure

Pekka Enberg (1):
      Merge branches 'topic/slab/fixes' and 'topic/slub/fixes' into for-linus
