Message-ID: <1464087628-7318-1-git-send-email-vdavydov@virtuozzo.com> Date: Tue, 24 May 2016 14:00:28 +0300 From: Vladimir Davydov <vdavydov@...tuozzo.com> To: Andrew Morton <akpm@...ux-foundation.org> CC: Michal Hocko <mhocko@...nel.org>, Tetsuo Handa <penguin-kernel@...ove.SAKURA.ne.jp>, <linux-mm@...ck.org>, <linux-kernel@...r.kernel.org> Subject: [PATCH] mm: oom: do not reap task if there are live threads in threadgroup If the current process is exiting, we don't invoke oom killer, instead we give it access to memory reserves and try to reap its mm in case nobody is going to use it. There's a mistake in the code performing this check - we just ignore any process of the same thread group no matter if it is exiting or not - see try_oom_reaper. Fix it.
