The current CPUsets code supports hierarchies, and I believe that
there are people out there who depend on them (right, PaulJ?) Since
CPUsets are at heart a form of resource controller, it would be nice
to have them use the same resource control infrastructure as other
resource controllers (see the generic container patches that I sent
out as an example of this). So that would be at least one user that
requires a hierarchy.
