Yes.

Sorry for the poor explanation.
I just thought that it wouldn't be bad to allow "each cpuset whose
cpu_exclusive attribute is mark true" to have its clones like the
figure below. In this case, cpu-2 and cpu-3 will be used exclusively
for the clones --- CPUSET 1, 2, and 3 ---.

I guess it seems very similar to one of your ideas except for reusing
cpu_exclusive flag. Do you think reusing the flag is good idea?

| | | |
CPUSET 0 CPUSET 1 CPUSET 2 CPUSET 3
sched domain A sched domain B sched domain B sched domain B
cpus: 0, 1 cpus: 2, 3 cpus: 2, 3 cpus: 2, 3
cpu_exclusive cpu_exclusive cpu_exclusive cpu_exclusive
meter_cpu meter_cpu meter_cpu
<------should we call it resouce domain?------>


Thanks,
Hirokazu Takahashi.
