Even if there isn't an actual race, the comment is dead wrong. I'm
reverting the following three patches. Let's try again later.
7e381b0eb1 ("cgroup: Drop task_lock(parent) on cgroup_fork()")
7e3aa30ac8 ("cgroup: Remove task_lock() from cgroup_post_fork()")
c84cdf75cc ("cgroup: Remove unnecessary task_lock before fetching css_set on migration")
Thanks.
