This is an internal function meant to return the number of avaliable processor where the process can scheduled, different than the __get_nprocs which returns a the system available online CPU. The Linux implementation currently only calls __get_nprocs(), which in tuns calls sched_getaffinity. Reviewed-by: Florian Weimer <fweimer@redhat.com>
