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.
