v9:
  - Add a new patch 1 to remove the child cpuset restriction on parent's
    "cpuset.cpus".
  - Relax initial root partition entry limitation to allow cpuset.cpus to
    overlap that of parent's.
  - An "isolated invalid" displayed type is added to
    cpuset.cpus.partition.
  - Resetting partition root to "member" will leave child partition root
    as invalid.
  - Update documentation and test accordingly.

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.

This patchset includes one bug fix and four enhancements to the cpuset v2 code.

  Patch 1: Allow parent to set "cpuset.cpus" that may not be a superset
  of children's "cpuset.cpus" for default hierarchy.

  Patch 2: Enable partition with no task to have empty cpuset.cpus.effective.

  Patch 3: Refining the features and constraints of a cpuset partition
  clarifying what changes are allowed.

  Patch 4: 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 5: Enable the "cpuset.cpus.partition" file to show the reason
  that causes invalid partition like "root invalid (No cpu available
  due to hotplug)".

Patch 6 updates the cgroup-v2.rst file accordingly. Patch 7 adds a new
cpuset test to test the new cpuset partition code.

Hi,

Is this patch series good enough or is there other changes you would 
still like to make in this series?

Cheers,
Longman
