I think that it's providing a sufficiently different control from
existing subsystems that making it a separate subsystem is reasonable.
The cpuset subsystem definitely doesn't sound like the right place,
since it's more dealing with numa isolation/policy. The cpu subsystem
could be, since it also deals with scheduling stuff.
