Title:
  cpuset_regression_test in ubuntu_ltp_controllers failed with "TBROK:
  Both cpuset.cpu_exclusive and cpu_exclusive do not exist" on J/K

Status in ubuntu-kernel-tests:
  Fix Released

Bug description:
  Issue found on Jammy 5.15.0-47.51 (only on Jammy, works with older
  kernels)

  With LTP fork updated (bug 1982995) with Luke's fix for cgroups, this
  test is no longer failing with:

  mount: /tmp/ltp-fEJNr5GDB8/LTP_cpuset_regression_test.6l9pALogpn/cpuset_test: cpuset already mounted or mount point busy.
  cpuset_regression_test 1 TBROK: mount -t cpuset cpuset cpuset_test failed
  umount: cpuset_test: not mounted.

  It's now failing with:
