Applied 1 to cgroup/for-7.1-fixes.

For 2, a cpuset test doesn't belong under selftests/sched_ext, but
selftests/cgroup doesn't have the machinery to host a sched_ext-based test
either, so there's no good home for it right now. If the rollback path can
be exercised without a BPF scheduler, please rewrite it that way and resend
targeting selftests/cgroup.

Thanks.
