Ravikiran G Thirumalai b5d8ca7c50 [PATCH] slab: remove cachep->spinlock 
Remove cachep->spinlock.  Locking has moved to the kmem_list3 and most of
the structures protected earlier by cachep->spinlock is now protected by
the l3->list_lock.  slab cache tunables like batchcount are accessed always
with the cache_chain_mutex held.

Patch tested on SMP and NUMA kernels with dbench processes running,
constant onlining/offlining, and constant cache tuning, all at the same
time.
