rcu: Add synchronous grace-period waiting for RCU-tasks
It turns out to be easier to add the synchronous grace-period waiting functions to RCU-tasks than to work around their absense in rcutorture, so this commit adds them. The key point is that the existence of call_rcu_tasks() means that rcutorture needs an rcu_barrier_tasks(). Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
