Subject: [PATCH tip/core/rcu 02/10] rcutorture: Add checks for stall ending before dump start

From: "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com>

The current rcutorture scripting checks for actual stalls (via the "Call
Trace:" check), but fails to spot the case where a stall ends just as it
is being detected.  This commit therefore adds a check for this case.
