Subject: Re: [this_cpu_xx V7 0/8] Per cpu atomics in core allocators and
 cleanup

Small fixup patch to the slub patches:

Subject: Update remaining reference to get_cpu_slab

If CONFIG_SLUB_STATS is set then some additional code is being
compiled that was not updated since it was a recent addition to slub.

Signed-off-by: Christoph Lameter <cl@...ux-foundation.org>
