From 7d613f6a39f2d53f26dbd40c4c78d1a9ea8de993 Mon Sep 17 00:00:00 2001
From: Peter Dufault <dufault@FreeBSD.org>
Date: Wed, 3 May 1995 18:09:20 +0000
Subject: Moved unit definitions out of scsiconf.h; Added CONTROL device that
 only does user-ioctl and nothing else; Added protection so user-ioctl
 requires write access; Clean up scsiconf.h a little. It needs more work.
