Yeah - I suppose cpusets could use it, though it's not critical. A fair bit of work already went into cpusets so that it would not need to traverse this hierarchy on any critical code path, or while holding inconvenient locks. So cpusets shouldn't be the driving motivation for this, but it will likely be happy to go along for the ride. -- I won't rest till it's the best ...
