McKenney <paulmck@xxxxxxxxxxxxx> CommitDate: Tue, 27 Nov 2018 09:21:38 -0800 cpufreq/intel_pstate: Replace synchronize_sched() with synchronize_rcu() Now that synchronize_rcu() waits for preempt-disable regions of code as well as RCU read-side critical sections, synchronize_sched() can be replaced by synchronize_rcu(). This commit therefore makes this change. Signed-off-by: Paul E.
