Ie nonpagable kernel allocations come from one zone, atomic allocations from another and user from yet another. It's basically the same thing that the slab does, except for pages. The key advantage is that allocations of different types are not mixed, so the lifetime of allocations in the same zone tends to be similar and fragmentation tends to be lower. -ben -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
