Subject: [PATCH 0/8] OOM killer/reaper changes for avoiding OOM lockup problem.
Date: Tue,  3 Jul 2018 23:25:01 +0900	[thread overview]
Message-ID: <1530627910-3415-1-git-send-email-penguin-kernel@I-love.SAKURA.ne.jp> (raw)

This series provides

  (1) Mitigation and a fix for CVE-2016-10723.

  (2) A mitigation for needlessly selecting next OOM victim reported
      by David Rientjes and rejected by Michal Hocko.

  (3) A preparation for handling many concurrent OOM victims which
      could become real by introducing memcg-aware OOM killer.

Tetsuo Handa (7):
  mm,oom: Don't call schedule_timeout_killable() with oom_lock held.
  mm,oom: Check pending victims earlier in out_of_memory().
  mm,oom: Fix unnecessary killing of additional processes.
  mm,page_alloc: Make oom_reserves_allowed() even.
  mm,oom: Bring OOM notifier to outside of oom_lock.
  mm,oom: Make oom_lock static variable.
  mm,oom: Do not sleep with oom_lock held.
Michal Hocko (1):
  mm,page_alloc: Move the short sleep to should_reclaim_retry().
