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 Cc: Michal Hocko <mhocko@kernel.org> Cc: Vladimir Davydov <vdavydov.dev@gmail.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Cc: David Rientjes <rientjes@google.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Tejun Heo <tj@kernel.org> Cc: kernel-team@fb.com Cc: cgroups@vger.kernel.org Cc: linux-doc@vger.kernel.org Cc: linux-kernel@vger.kernel.org Cc: linux-mm@kvack.org Roman Gushchin (5): 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 mm, oom: cgroup v2 mount option to disable cgroup-aware OOM killer Documentation/admin-guide/kernel-parameters.txt | 1 + Documentation/cgroup-v2.txt | 56 +++++ include/linux/memcontrol.h | 36 +++ include/linux/oom.h | 12 +- mm/memcontrol.c | 293 ++++++++++++++++++++++++ mm/oom_kill.c | 209 +++++++++++------ 6 files changed, 537 insertions(+), 70 deletions(-) -- 2.13.5
