From c7100f5427c83eff7e8fb092a56cc25524f1454a Mon Sep 17 00:00:00 2001
From: Matthew Dempsky <matthew@cvs.openbsd.org>
Date: Sun, 5 Jun 2011 18:40:34 +0000
Subject: Drop kernel support for the useless DIOCWLABEL ioctl and prune a lot
 of silly flag twiddling code in various disk drivers.

ok deraadt@, miod@

N.B., users will need a -current disklabel(8) to be able to write new
disklabels to disk now.
