[PATCH] slub: nr_slabs is an atomic_long_t

[Stephen Rothwell <sfr@canb.auug.org.au>]

so shouldn't be passed to atomic_read.

mm/slub.c: In function 'slab_mem_offline_callback':
mm/slub.c:2737: warning: passing argument 1 of 'atomic_read' from incompatible pointer type
mm/slub.c:2737: warning: passing argument 1 of 'atomic_read' from incompatible pointer type
