[PATCH v2 0/2] cgroup/cpuset: Make hotplug code more efficient

[Waiman Long]

 v2:
  - It turns out it works around the v1 cpuset missing offline cpu
    problem better than I originally thought. So the patch description
    is updated accordingly.

This small patch series makes the cpuset hotplug a bit more efficient
by eliminating unnecessary task iteration and cpu/node masks update
when a cpu hotplug event (online/offline) happens.

It can also largely work around the known problem of missing previously
offlined cpus in v1 cpuset with some exceptions.

Waiman Long (2):
  cgroup/cpuset: Skip task update if hotplug doesn't affect current
    cpuset
  cgroup/cpuset: Don't update tasks' cpumasks for cpu offline events
