That is not what I meant. I would like more higher order allocations to succeed. That does not mean that slubs allocation methods and flags passed have to stay the same. You can change the slub behavior if it helps. I am just suspicious of compaction. If these mods are needed to reduce the amount of higher order pages then compaction does not have the beneficial effect that it should have. It does not actually increase the available higher order pages. Fix that first. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
