Subject: [PATCH 46/49] ext4: Change all super.c messages to print the device
From: Eric Sandeen <sandeen@...hat.com>
This patch changes ext4 super.c to include the device name with all
warning/error messages, by using a new utility function ext4_msg.
It's a rather large patch, but very mechanic. I left debug printks
alone.
This is a straightforward port of a patch which Andi Kleen did for
ext3.
