Subject: [PATCH tip/core/rcu 02/12] rcu: Remove show_tiny_preempt_stats()
Date: Fri, 12 Apr 2013 16:48:21 -0700 [thread overview]
Message-ID: <1365810511-24811-2-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, show_tiny_preempt_stats()
is now an empty function. This commit therefore eliminates it by
inlining it.
