rcu: Don't spawn rcub kthreads on root rcu_node structure Now that offlining CPUs no longer moves leaf rcu_node structures' ->blkd_tasks lists to the root, there is no way for the root rcu_node structure's ->blkd_task list to be nonempty, unless the root node is also the sole leaf node. This commit therefore refrains from creating an rcub kthread for the root rcu_node structure unless it is also the sole leaf. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
