v8:
  - Reorganize the patch series and rationalize the features and
    constraints of a partition.
  - Update patch descriptions and documentation accordingly.

v7:
  - Simplify the documentation patch (patch 5) as suggested by Tejun.
  - Fix a typo in patch 2 and improper commit log in patch 3.

v6:
  - Remove duplicated tmpmask from update_prstate() which should fix the
    frame size too large problem reported by kernel test robot.

This patchset makes four enhancements to the cpuset v2 code.

  Patch 1: Enable partition with no task to have empty cpuset.cpus.effective.

  Patch 2: Refining the features and constraints of a cpuset partition
  clarifying what changes are allowed.

  Patch 3: Add a new partition state "isolated" to create a partition
  root without load balancing. This is for handling intermitten workloads
  that have a strict low latency requirement.

  Patch 4: Enable the "cpuset.cpus.partition" file to show the reason
  that causes invalid partition like "root invalid (No cpu available
  due to hotplug)".

Patch 5 updates the cgroup-v2.rst file accordingly. Patch 6 adds a new
cpuset test to test the new cpuset partition code.
