[PATCH v2 0/2] cgroup/cpuset: Miscellaneous fixes and cleanups

[Waiman Long <longman@redhat.com>]

 v2:
  - Update patch 1 as suggested by Ridong Chen and add new test cases.
  - Minor update to patch 2 code and comment log.

Patch 1 updates compute_effective_cpumask() and adds new
compute_effective_nodemask() helper to make sure that effective_cpus
and effective_mems will inherit parent's versions for v2 if
cpuset.cpus/cpuset.mems is empty.

Patch 2 makes cpuset_update_tasks_nodemask() to perform memory rebind
and migration only for thread group leader like cpuset_attach().

Waiman Long (2):
  cgroup/cpuset: Avoid unnecessary cpus & mems update in
    cpuset_hotplug_update_tasks()
  cgroup/cpuset: Rebind/migrate mm only for threadgroup leader in
    cpuset_update_tasks_nodemask()
