I don't see why user code needs to determine NR_CPUS exactly. Any reasonable upper bound should work - reasonable meaning doesn't waste too many unused words of memory.
It's not really NR_CPUS that users need - its a reasonably close upper bound to the size of the space that sched_getaffinity() must be provided they need. And your code does a pretty good job of providing that.
