McKenney Date: Fri Jul 11 11:30:24 2014 -0700 rcu: Create rcuo kthreads only for onlined CPUs RCU currently uses for_each_possible_cpu() to spawn rcuo kthreads, which can result in more rcuo kthreads than one would expect, for example, derRichard reported 64 CPUs worth of rcuo kthreads on an 8-CPU image. This commit therefore creates rcuo kthreads only for those CPUs that actually come online. This was reported by derRichard on the OFTC IRC network.
