SLUB is also "dismissing" lots of other NUMA locality requirements since
it relies on the page allocators for this. SLUB does *not* realize memory
policy and/or cpuset support for individual objects. NUMA locality is
implemented only (aside from explicit requests of memory from a
certain node) when slab page allocations are performed.
