[GIT PULL] SLAB changes for v3.7-rc0

[GIT PULL] SLAB changes for v3.7-rc0

[Pekka Enberg]

Hi Linus,

Please pull the latest SLAB tree from:

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

New and noteworthy:

  * More SLAB allocator unification patches from Christoph Lameter and
    others.  This paves the way for slab memcg patches that hopefully
    will land in v3.8.

  * SLAB tracing improvements from Ezequiel Garcia.

  * Kernel tainting upon SLAB corruption from Dave Jones.

  * Miscellanous SLAB allocator bug fixes and improvements from various
    people.

			Pekka

Pekka,

what are your plans with 

	https://lkml.org/lkml/2012/10/3/285

please? It'd be nice to have it in Linus' tree reasonably soon, otherwise 
we'll be receiving false positive lockdep reports over and over again.

Thanks,
