Let's drop "_unbounds" postfix and name it just "cpumask". We don't apply it to per-cpu workqueues now but that really is an implementation detail and later when (and if) we actually distinguish per-cpu usages for correctness from for optimization, we may as well apply the same cpumask to per-cpu ones too. Another thing with naming is that I didn't anticipate having attributes at the top directory so the workqueue directories aren't namespaced. Maybe we want to namespace top level knobs? "system_cpumask" maybe? Any better ideas?
