Subject: [Qemu-devel] [PATCH v3 01/11] fdc: move pick_geometry
Date: Wed, 16 Dec 2015 17:16:07 -0500	[thread overview]
Message-ID: <1450304177-3935-2-git-send-email-jsnow@redhat.com> (raw)
In-Reply-To: <1450304177-3935-1-git-send-email-jsnow@redhat.com>

Code motion: I want to refactor this function to work with FDrive
directly, so shuffle it below that definition.
