From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lu Jialin Subject: [PATCH -next] mm/memcontrol.c: remove unused private flag of memory.oom_control Date: Thu, 21 Apr 2022 20:27:55 +0800 Message-ID: <20220421122755.40899-1-lujialin4@huawei.com> Mime-Version: 1.0 Return-path: List-ID: Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Johannes Weiner , Andrew Morton , Michal Hocko , Roman Gushchin , Shakeel Butt Cc: Lu Jialin , Wang Weiyang , cgroups-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-mm-Bw31MaZKKs3YtjvyW6yDsg@public.gmane.org There is no use for the private value, __OOM_TYPE and OOM notifier OOM_CONTROL. Therefore remove them to make the code clean.
