From 25c36329a30c8cac090effe1fbae9bb916fa95fe Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 3 May 2017 09:51:55 -0700 Subject: rcu: Move expediting-related access/control out of rcupdate.h The rcu_gp_is_normal(), rcu_gp_is_expedited(), rcu_expedite_gp(), and rcu_unexpedite_gp() functions are intended only for use within the RCU implementation itself -- the sysfs access is what should be used outside of RCU. This commit therefore moves the declarations for these functions to kernel/rcu/rcu.h, and also includes this file into kernel/rcu/rcutorture.c and kernel/rcu/rcuperf.c. This also has the beneficial effect of shrinking rcupdate.c a bit. Reported-by: Ingo Molnar Signed-off-by: Paul E.
