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
