Subject: [PATCH tip/core/rcu 7/7] rcu: Move early boot callback tests earlier
Date: Tue,  3 Mar 2015 08:45:48 -0800	[thread overview]
Message-ID: <1425401148-7848-7-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <1425401148-7848-1-git-send-email-paulmck@linux.vnet.ibm.com>

From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

Because callbacks can now be posted quite early in boot, move the
early boot callback tests to precede RCU initialization.
