I wonder if we could make the collector per-cpuset.

I suppose this is because cpuset's offer some middle ground between collecting data per-cpu
vs. collecting it for all cpus (as being done now) ?

What happens when someone is using cpusets on such a machine and changes its membership in response to other needs. All taskstats users would need to monitor for such changes and adjust their processing....seems like unnecessary tying up of two unrelated concepts.
