Subject: [PATCH tip/core/rcu 09/12] rcu: Remove rcu_preempt_note_context_switch()
Date: Fri, 12 Apr 2013 16:48:28 -0700 [thread overview]
Message-ID: <1365810511-24811-9-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_note_context_switch()
is now an empty function. This commit therefore eliminates it by inlining it.
