Recently 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: better name mem_cgroup_out_of_memory()
  mm, memcg: don't try to kill a process if memcg is not populated
