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
