I think making shrinking decision per-zone is fine. But do we need to duplicate all the lru lists and infrastructure per-zone for that instead of simply per-zone? Even with per-node lists we can easily skip over items from the wrong zone. Given that we have up to 6 zones per node currently, and we would mostly use one with a few fallbacks that seems like a lot of overkill. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
