Subject: [cgroup/for-6.19 PATCH v2 0/3] cgroup/cpuset: Additional housekeeping check & cleanup

 v2: Update patch 2 to correct some of the checking code and add
     prstate_housekeeping_conflict() as suggested by Chen Ridong.

The first two patches are based on the two cpuset patches from the
"timers: Exclude isolated cpus from timer migration" patch series [1]
with some modifications. They add additional nohz_full housekeeping
mask check to ensure that there is at least one common housekeeping
CPU that is not domain and nohz_full isolated.

The last patch is another cleanup patch to simplify the current
partition code.

Gabriele Monaco (1):
  cgroup/cpuset: Rename update_unbound_workqueue_cpumask() to
    update_isolation_cpumasks()

Waiman Long (2):
  cgroup/cpuset: Fail if isolated and nohz_full don't leave any
    housekeeping
  cgroup/cpuset: Globally track isolated_cpus update
