There are only a few lower zones on a NUMA machine anyways and if the filtering in __alloc_pages does the trick then we could simply generate lists will all zones in build_bindzonelist. The main dividing line may be if zones are available on all (memory) nodes. If they are only available on a single nodes (like DMA or DMA32) then policies must be disregarded if the alloc would otherwise not be possible. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
