Message-ID: <1382990001.8718.4.camel@joe-AO722>
Date: Mon, 28 Oct 2013 12:53:21 -0700
From: Joe Perches <joe@...ches.com>
To: netdev <netdev@...r.kernel.org>
Cc: LKML <linux-kernel@...r.kernel.org>
Subject: [PATCH net-next] netconsole: Convert to pr_<level>
Use a more current logging style.
Convert printks to pr_<level>.
Consolidate multiple printks into a single printk to avoid
any possible dmesg interleaving. Add a default "event" msg
in case the listed types are ever expanded.
