Subject: [PATCH v2 0/2]memcg oom: don't try to kill a process if there is no process
Date: Mon, 4 May 2020 00:26:19 -0400 [thread overview]
Message-ID: <20200504042621.10334-1-laoar.shao@gmail.com> (raw)
ecently Shakeel reported a issue which also confused me serveral months
earlier that it still try to kill a process even if there is no process.
If a memcg is not populated, it is useless to try to kill a process.
mem_cgroup_out_of_memory() is renamed to mem_cgroup_oom_kill() for better
understanding.
Yafang Shao (2):
mm, memcg: rename mem_cgroup_out_of_memory()
mm, memcg: don't try to kill a process if memcg is not populated
