Subject: [PATCH -mm 0/3] mm/oom_kill: ensure we actually kill all tasks sharing the same mm
Date: Tue, 29 Sep 2015 16:17:58 +0200 [thread overview]
Message-ID: <20150929141758.GA10934@redhat.com> (raw)
Michal, Tetsuo, David, sorry for delay. I'll try to read and answer
your emails in "can't oom-kill zap the victim's memory" thread later.
Let me send some initial changes which imo makes sense regardless,
but if we want to zap the victim's memory we need to ensure that all
tasks which share this ->mm were actually killed (see 3/3).
Please review, this series is simple but only compile tested.
Andrew, this is on top of linux-mmotm.git + the recent mm-oom-remove-
task_lock-protecting-comm-printing.patch from David.
Oleg.
