From 2a42a37abfb8365d91c89405905262660f971094 Mon Sep 17 00:00:00 2001 From: John Snow Date: Fri, 22 Jan 2016 15:50:57 -0500 Subject: fdc: add disk field Currently, 'drive' is used both to represent the current diskette type as well as the current drive type. This patch adds a 'disk' field that is updated explicitly to match the type of the disk. As of this patch, disk and drive are always the same, but forthcoming patches to change the behavior of pick_geometry will invalidate this assumption. disk does not need to be migrated because it is not user-visible state nor is it currently used for any calculations. It is purely informative, and will be rebuilt automatically via fd_revalidate on the new host.
