Message-ID: <4C49FA4E.80109@redhat.com>
Date: Fri, 23 Jul 2010 15:23:42 -0500
From: Eric Sandeen <sandeen@...hat.com>
To: ext4 development <linux-ext4@...r.kernel.org>
Subject: [PATCH] ext4: fix ext4_get_blocks references
ext4_get_blocks got renamed to ext4_map_blocks, but left stale
comments and a prototype littered around.
Signed-off-by: Eric Sandeen <sandeen@...hat.com>
