Subject: [PATCH RFC tip/core/rcu 5/7] rcu: remove redundant rcu_cpu_stall_suppress declaration
Date: Sat, 3 Dec 2011 10:34:40 -0800 [thread overview]
Message-ID: <1322937282-19846-5-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20111203183417.GA18914@linux.vnet.ibm.com>
No point in having two identical rcu_cpu_stall_suppress declarations,
so remove the more obscure of the two.
Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
