I have already explained why I have acked it. I will not repeat it here again. I have also proposed an alternative solution (https://lkml.org/lkml/2013/12/12/174) which IMO is more viable because it handles both user/kernel memcg OOM consistently. This patch still has to be discussed because of other Johannes concerns. I plan to repost it in a near future. -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
