From c1ef9f83c919949e90841ae0990aa9a0273d6490 Mon Sep 17 00:00:00 2001
From: julian <julian@FreeBSD.org>
Date: Thu, 3 Dec 1998 02:27:35 +0000
Subject: Reviewed by:	Don Lewis <Don.Lewis@tsc.tdk.com> Submitted by:	Kirk
 McKusick <mckusick@McKusick.COM> Obtained from:	Mckusick, BSDI and a
 host of others

This exactly matches Kirks sources imported under the
Tag MCKUSICK2. These are as supplied by kirk with one small
change needed to compile under freeBSD.

Some FreeBSD patches will be added back, though many have been
added to Kirk's sources already.
