My preliminary analysis is that the warning may be caused by my commit 1f1562fcd04a ("cgroup/cpuset: Don't let child cpusets restrict parent in default hierarchy") since the merge branch e5313968c41b is missing the fix commit d068eebbd482 ("cgroup/cpuset: Make child cpusets restrict parents on v1 hierarchy"). I believe the problem should be gone once the merge branch is updated to a later upstream baseline.
Cheers, Longman
