By my reading that does not give what we want here. In a machine with eight CPUs and all are down but CPU7, then num_online_cpus() will return 1. In the light of the nonlinear/hotplug CPU work in 2.5, I think looping up to NR_CPUS and checking cpu_online really is the right way to do it. (But I know much less about it than other people.) -- Martin
