Thanks for the clarification, that makes sense to me now. It doesn't look like the patch handles CPU hotplugging though; a cpumask filled with *only* offline CPUs can be passed as a parameter, or all of the CPUs in the cpumask can be offlined after the setup is finished. This isn't a problem with the default behavior because num_possible_cpus() guarantees that there will always be at least one online CPU for the nvme queue (since the CPU hotplug code doesn't allow all CPUs to be offlined).
