Then, please revert "mm, oom: hide mm which is shared with kthread or global init"
( http://lkml.kernel.org/r/1466426628-15074-11-git-send-email-mhocko@kernel.org ).
I don't like that patch because it is doing pointless find_lock_task_mm() test
and is telling a lie because it does not guarantee that we won't hit OOM livelock.
Merging patches with a known lie is sand in eyes.
