From 6d5a228d7f9879b6376575687c6e307e43105f72 Mon Sep 17 00:00:00 2001
From: msmith <msmith@FreeBSD.org>
Date: Wed, 9 Jan 2002 03:39:04 +0000
Subject: Define the kern.cam sysctl in the cam layer, rather than multiply in
 several peripheral drivers.  Remove Ken's comment to the effect that this
 needed to be done.

Staticise camnet_ih and cambio_ih.
