This patchset makes the OOM killer cgroup-aware. Patches 1-3 are simple refactorings of the OOM killer code, required to reuse the code in the memory controller. Patches 4 & 5 are introducing new memcg settings: oom_kill_all_tasks and oom_score_adj. Patch 6 introduces the cgroup-aware OOM killer. Patch 7 is docs update. v1: https://lkml.org/lkml/2017/5/18/969 v2: - Reworked victim selection based on feedback from Michal Hocko, Vladimir Davydov and Johannes Weiner - "Kill all tasks" is now an opt-in option, by default only one process will be killed - Added per-cgroup oom_score_adj - Refined oom score calculations, suggested by Vladimir Davydov - Converted to a patchset Roman Gushchin (7): mm, oom: refactor select_bad_process() to take memcg as an argument mm, oom: split oom_kill_process() and export __oom_kill_process() mm, oom: export oom_evaluate_task() and select_bad_process() mm, oom: introduce oom_kill_all_tasks option for memory cgroups mm, oom: introduce oom_score_adj for memory cgroups mm, oom: cgroup-aware OOM killer mm,oom,docs: describe the cgroup-aware OOM killer Documentation/cgroup-v2.txt | 47 ++++++++- include/linux/memcontrol.h | 19 ++++ include/linux/oom.h | 6 ++ mm/memcontrol.c | 247 ++++++++++++++++++++++++++++++++++++++++++++ mm/oom_kill.c | 137 +++++++++++++----------- 5 files changed, 392 insertions(+), 64 deletions(-) -- 2.7.4 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
