Message-Id: <1283467794.4378.17.camel@odc-laptop>
Date: Thu, 02 Sep 2010 15:49:54 -0700
From: David Cross <david.cross@...ress.com>
To: greg@...ah.com
Cc: linux-kernel@...r.kernel.org
Subject: Re: [PATCH] West Bridge Astoria Driver 2.6.35, minor block and
device driver updates
This patch contains minor updates to the west bridge block and device
drivers, including the addition of a common lock and a minor update to
remove the blk_fs_request call based on a kernel update. These changes
could possibly be separated, but are very minor in scope and as such
have been submitted together.
Thanks,
David
