Subject: [PATCH tip/core/rcu 15/17] rcu: Fix __rcu_reclaim() to use true/false for bool
Date: Mon, 7 Jul 2014 15:38:19 -0700 [thread overview]
Message-ID: <1404772701-8804-15-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <1404772701-8804-1-git-send-email-paulmck@linux.vnet.ibm.com>
From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>
The __rcu_reclaim() function returned 0/1, which is not proper for a
function of type bool. This commit therefore converts to false/true.
