Subject: [PATCH rcu 09/16] rcu/rcuscale: Use call_rcu_hurry() for async reader test
From: "Joel Fernandes (Google)" <joel@...lfernandes.org>
rcuscale uses call_rcu() to queue async readers. With recent changes to
save power, the test will have fewer async readers in flight. Use the
call_rcu_hurry() API instead to revert to the old behavior.
