I've had it with this crap. If cpuacct can really go away, that's great, but I don't think the problem at hand is unsolvable, so let's not jump it. cpuacct and cpu aren't the onlfy problem cases after all. We need to solve it for other controllers too. Thanks. -- tejun -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
