From: Sha Zhengju <handai.szj@xxxxxxxxxx> When memcg oom is happening the current memcg related dump information is limited for debugging. The patches provide more detailed memcg page statistics and also take hierarchy into consideration. The previous primitive version can be reached here: https://lkml.org/lkml/2012/7/30/179. Change log: 1. some modification towards hierarchy 2. rework dump_tasks 3. rebased on Michal's mm tree since-3.6 Any comments are welcomed. : ) Sha Zhengju (2): memcg-oom-provide-more-precise-dump-info-while-memcg.patch oom-rework-dump_tasks-to-optimize-memcg-oom-situatio.patch include/linux/memcontrol.h | 7 ++++ include/linux/oom.h | 2 + mm/memcontrol.c | 85 +++++++++++++++++++++++++++++++++++++++----- mm/oom_kill.c | 61 +++++++++++++++++++------------ 4 files changed, 122 insertions(+), 33 deletions(-) -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
