From 86aea0e6e7d571a9452082a7198d0603cc5dd965 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 21 Oct 2014 08:12:00 -0700 Subject: rcu: Remove "cpu" argument to rcu_preempt_check_callbacks() Because rcu_preempt_check_callbacks()'s argument is guaranteed to always be the current CPU, drop the argument and replace per_cpu() with __this_cpu_read().
