From 120ff80663185654fbfe0a71b2d968cd400c82d9 Mon Sep 17 00:00:00 2001
From: phk <phk@FreeBSD.org>
Date: Sun, 4 Dec 1994 19:58:43 +0000
Subject: Implemented a "TEXT_SET" called 'cleanup_set' which will be called
 before the reboot takes place (if not RB_NOSYNC that is).  The vn driver
 needs this. Other places might benefit too.
