No, soft offlining can still allow accesses for some time. It'll never kill anything. Hard tries much harder and will kill. In some cases (unshrinkable kernel allocation) they end up doing the same because there isn't any other alternative though. However these are expected to only apply to a small percentage of pages in a typical system. -Andi -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
