Revision 855b018325737f7691f9b7d86339df40aa4e47c3 authored by Michal Hocko on 25 March 2016, 21:20:36 UTC, committed by Linus Torvalds on 25 March 2016, 23:37:42 UTC
Tetsuo has reported that oom_kill_allocating_task=1 will cause oom_reaper_list corruption because oom_kill_process doesn't follow standard OOM exclusion (aka ignores TIF_MEMDIE) and allows to enqueue the same task multiple times - e.g. by sacrificing the same child multiple times. This patch fixes the issue by introducing a new MMF_OOM_KILLED mm flag which is set in oom_kill_process atomically and oom reaper is disabled if the flag was already set.
