rcu: Fix obsolete priority-boosting comment Tasks are no longer migrated to the root rcu_node, so there is no longer any need for a boost kthread for the root rcu_node, and there no longer is such a kthread. This commit therefore fixes the comment in rcu_boost_kthread()'s header to reflect this new reality. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
