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

Posted by Waiman Long 2 years, 7 months ago

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

These patches can also avoid the known problem of missing a previously
gone offline cpu in v1 cpuset after a single cpu offline and online
sequence.

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
