[PATCH-next 0/5] cgroup/cpuset: Fix various housekeeping check problems

[Waiman Long <longman@redhat.com>]

Commit 4a74e418881f ("cgroup/cpuset: Check partition conflict with
housekeeping setup") and commit 103b08709e8a ("cgroup/cpuset: Fail if
isolated and nohz_full don't leave any housekeeping") add housekeeping
checks to fail partition changes that will violate the housekeeping
rules. However there are several issues that make the check incomplete
and missing in some cases. This series fixes the various known
housekeeing check issues and adds additional test cases in
test_cpuset_prs.sh to test for some of those issues.

Waiman Long (5):
  cgroup/cpuset: Consolidate isolated_cpus_can_update() into
    prstate_housekeeping_conflict()
  cgroup/cpuset: Consider all the exclusive CPUs when doing housekeeping
    check
  cgroup/cpuset: Do housekeeping check before converting invalid
    partition to valid
  cgroup/cpuset: Properly disabling partition when partition state
    switching fails
  selftests/cgroup: Add tests for housekeeping check
