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.
