Applied to cgroup/for-7.3.
The patch was generated against a base which predates 866f587e9c70
("cgroup/cpuset: Avoid unnecessary cpus & mems update in
cpuset_hotplug_update_tasks()") and no longer applied, so I moved the
new entry to keep it with the other sibling-exclusion cases and matched
the current column alignment. The applied change follows:
