From: "Paul E. McKenney" <paulmck@xxxxxxxxxx> There is code in rcu_implicit_dynticks_qs() that checks for the current grace period being halfway to the RCU CPU stall timeout, but rcutorture currently does not test this code. This commit therefore adds a 14-second stall to the TREE07 scenario in order to test this code given the default RCU CPU stall warning timeout of 21 seconds. Signed-off-by: Paul E.
