So I've double checked and I was wrong blaming this commit. Back then it
was tasklist_lock to protect us from releasing the task. It's been only
since 6b0c81b3be11 ("mm, oom: reduce dependency on tasklist_lock") that
we rely on the reference counting and unless I am missing something this
is also the commit which has introduced this bug.
