Are you suggesting that we add a cpuset.cpus.events file that allows
processes to be notified if an event (e.g. hotplug) that changes a partition
root to invalid partition happens or when explicit change to a partition
root fails? Will that be enough to satisfy your requirement?

Yeah, something like that or make the current state file generate events on
state transitions.

Sure. I will change the patch to make cpuset.cpus.partition generates 
event when its state change. Thanks for the suggestion. It definitely 
makes it better.

Cheers,
