One argument for removing it from here is the maintainability. Now you have a memcg specific check which is not in sync with the oom. E.g. out_of_memory does task_will_free_mem as the very first thing. You are also automatically excluding oom killer for cases where that might make a sense.What makes it possible to remove this check? This check was added because task_will_free_mem() in out_of_memory() does NOT work. See commit 7775face207922ea ("memcg: killed threads should not invoke memcg OOM killer").
You are right. I've forgot about this and should have checked git blame. Thanks for bringing this up! -- Michal Hocko SUSE Labs
