rcu: Make rcu_torture_boost() exit loops at end of test
One of the loops in rcu_torture_boost() fails to check kthread_should_stop(), and thus might be slowing or even stopping completion of rcutorture tests at rmmod time. This commit adds the kthread_should_stop() check to the offending loop. Signed-off-by: Paul E. McKenney <paul.mckenney@linaro.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
