Date: Tue, 20 Aug 2013 11:50:02 +0800 From: Chen Gang <gang.chen@...anux.com> To: dipankar@...ibm.com, Paul McKenney <paulmck@...ux.vnet.ibm.com> CC: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: [PATCH] kernel/rcutree.c: deem to be lazy if there are no callbacks. According to the comment above rcu_cpu_has_callbacks(): "If there are no callbacks, all of them are deemed to be lazy". So when both 'hc' and 'al' are false, '*all_lazy' should be true, not false.
