From 47d65935a7f26f24417585e872e254c7ecc6596f Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 27 Mar 2013 09:05:34 -0700 Subject: [PATCH] rcu: Remove rcu_preempt_remove_callbacks() With the removal of CONFIG_TINY_PREEMPT_RCU, rcu_preempt_remove_callbacks() is now an empty function. This commit therefore eliminates it by inlining it. Signed-off-by: Paul E.
