Subject: [Qemu-devel] [PULL 02/13] fdc: move pick_geometry
Date: Mon, 25 Jan 2016 14:41:14 -0500	[thread overview]
Message-ID: <1453750885-16066-3-git-send-email-jsnow@redhat.com> (raw)
In-Reply-To: <1453750885-16066-1-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.
