[v5 0/4] cgroup-aware OOM killer
This patchset makes the OOM killer cgroup-aware. v5: - Rebased on top of Michal Hocko's patches, which have changed the way how OOM victims becoming an access to the memory reserves. Dropped corresponding part of this patchset - Separated the oom_kill_process() splitting into a standalone commit - Added debug output (suggested by David Rientjes) - Some minor fixes v4: - Reworked per-cgroup oom_score_adj into oom_priority (based on ideas by David Rientjes) - Tasks with oom_score_adj -1000 are never selected if oom_kill_all_tasks is not set - Memcg victim selection code is reworked, and synchronization is based on finding tasks with OOM victim marker, rather then on global counter - Debug output is dropped - Refactored TIF_MEMDIE usage v3: - Merged commits 1-4 into 6 - Separated oom_score_adj logic and debug output into separate commits - Fixed swap accounting 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 v1: https://lkml.org/lkml/2017/5/18/969 Roman Gushchin (4): mm, oom: refactor the oom_kill_process() function mm, oom: cgroup-aware OOM killer mm, oom: introduce oom_priority for memory cgroups mm, oom, docs: describe the cgroup-aware OOM killer Documentation/cgroup-v2.txt | 62 +++ include/linux/memcontrol.h | 36 ++ include/linux/oom.h | 3 + mm/memcontrol.c | 259 mm/oom_kill.c | 181 +-- 5 files changed, 484 insertions(+), 57 deletions(-) -- 2.13.5
