Title:
  ubuntu_ltp_controllers:cpuset_hotplug: write error: Operation not
  supported

Status in ubuntu-kernel-tests:
  New

Bug description:
  Seen on mcdivitt35-kernel.arm64 with xenial:linux-hwe(4.15) for
  sru-20210927. This is the first time ltp controllers are broken out,
  and it does not look like a kernel problem...
