From 723df859d8bba948ff2eb08eba32ab433acf7c9c Mon Sep 17 00:00:00 2001 From: "Joel Fernandes (Google)" Date: Sun, 16 Oct 2022 16:23:00 +0000 Subject: [PATCH] rcu/rcuscale: Use call_rcu_hurry() for async reader test 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.
