Its some overhead for SLAB (a lot is what? If you tune down the per cpu caches it should be a couple of pages) but its none for SLUB. Maybe we need to add the merge logic to SLAB?
Or maybe we can extract a common higher handling level for kmem_cache from all slab allocators and make merging standard.
