This doesn't make sense to me. If a task is to run on the CPUs in both sets A and B, then it has to be in both those cpusets, which isn't allowed, or in some super set of both A and B (that is, in this example, in the top cpuset), which doesn't restrict the task to just A or B or their union. I have no idea what distinction you are seeing between what _cpus_ a task can run on, and what cpuset it belongs to. -- I won't rest till it's the best ...
