Subject: [PATCH tip/core/rcu 07/13] rcu: Remove check_cpu_stall_preempt()
Date: Mon, 20 May 2013 07:58:14 -0700 [thread overview]
Message-ID: <1369061900-546-7-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <1369061900-546-1-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, check_cpu_stall_preempt()
is now an empty function. This commit therefore eliminates it by
inlining it.
