Sounds a bit contrived. Does it need to be something defined in the root
cgroup? The only thing that's needed is that a cgroup needs to claim CPUs
exclusively without using them, right? Let's say we add a new interface
file, say, cpuset.cpus.reserve which is always exclusive and can be consumed
by children whichever way they want, wouldn't that be sufficient? Then,
there would be nothing to describe in the root cgroup.

Thanks.
