| From | "Paul E. McKenney" <> | Subject | [PATCH rcu 08/16] rcu/sync: Use call_rcu_hurry() instead of call_rcu | Date | Wed, 30 Nov 2022 10:13:17 -0800 |

From: "Joel Fernandes (Google)" <joel@joelfernandes.org>
call_rcu() changes to save power will slow down rcu sync. Use the call_rcu_hurry() API instead which reverts to the old behavior.
