torture: Trace long read-side delays Although rcutorture will occasionally do a 50-millisecond grace-period delay, these delays are quite rare. And rightly so, because otherwise the read rate would be quite low. Thie means that it can be important to identify whether or not a given run contained a long-delay read. This commit therefore inserts a trace_rcu_torture_read() event to flag runs containing long delays. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
