Subject: [PATCH rcu 16/20] rcutorture:  Make scenario SRCU-P use srcu_read_lock_fast()

From: "Paul E. McKenney" <paulmck@...nel.org>

This commit causes the rcutorture SRCU-P scenario use the
srcu_read_lock_fast() and srcu_read_unlock_fast() functions.  This will
cause these two functions to be regularly tested by several developers
(myself included), for example, those who use torture.sh as an RCU
acceptance test.
