Subject: [PATCH 0/5] cgroup/cpuset: Miscellaneous updates

This patch series includes miscellaneous update to the cpuset and its
testing code.

Patch 2 is actually a follow-up of commit 3fb906e7fabb ("cgroup/cpuset:
Don't filter offline CPUs in cpuset_cpus_allowed() for top cpuset tasks").

Patches 3-4 are for handling corner cases when dealing with
task_cpu_possible_mask().

Waiman Long (5):
  cgroup/cpuset: Skip task update if hotplug doesn't affect current
    cpuset
  cgroup/cpuset: Include offline CPUs when tasks' cpumasks in top_cpuset
    are updated
  cgroup/cpuset: Find another usable CPU if none found in current cpuset
  cgroup/cpuset: Add CONFIG_DEBUG_CPUSETS config for cpuset testing
  cgroup/cpuset: Minor updates to test_cpuset_prs.sh
