This makes the code loops through all smp_cpus CPUs max_cpus times, instead of just looping through the smp_cpus CPUs once. I'm all for making the code simpler, and there's an upper bound: looking at CPU objects 64k times (because MAX_CPUMASK_BITS is 255). But I want to make sure we agree this is an optimization we want to drop. -- Eduardo
