From 7651d6b25086656eacfdd8356bfe3a21c0c2d79d Mon Sep 17 00:00:00 2001 From: "Joel Fernandes (Google)" Date: Sun, 16 Oct 2022 16:22:59 +0000 Subject: [PATCH] rcu/sync: Use call_rcu_hurry() instead of call_rcu call_rcu() changes to save power will slow down rcu sync. Use the call_rcu_hurry() API instead which reverts to the old behavior.
