From 3caec62fbb313946b9be53720bbf2280bb19ec28 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 3 May 2017 09:27:15 -0700 Subject: [PATCH] rcu: Move rcu_expedited and rcu_normal externs from rcupdate.h The rcu_expedited and rcu_normal variables are used only by sysctl and kernel/rcu/update.c, so it does not make sense to their extern declarations in rcupdate.h. This commit therefore moves these extern declarations to update.c. Reported-by: Ingo Molnar Signed-off-by: Paul E.
