Thanks for the info. However what I cares is the docker/KVM case. For
example, when I created docker on xenial 16.04, the container process
will still be added into /sys/fs/cgroup/cpuset/docker; When creating
KVM, the KVM process will be added into sub cpuset cgroup as well. As a
result, the issue can still impact those tasks.

For the above, is it already covered(on higher xenial version) or does
it need more consideration?
