Subject: [PATCH tip/core/rcu 04/12] rcu: Remove rcu_preempt_remove_callbacks()
Date: Fri, 12 Apr 2013 16:48:23 -0700	[thread overview]
Message-ID: <1365810511-24811-4-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <1365810511-24811-1-git-send-email-paulmck@linux.vnet.ibm.com>

From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

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.
