SLUB already uses that map on bootup through the page allocator. So for boot you can actually restrict slub without any additional patches. The problem is later when the policy is set to MPOL_DEFAULT. The key problem is that the node restrictions add an additional constraint to the ones that SLUB already obeys. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
