From 234c9175790c7227683cfddda32ec695ec593bd0 Mon Sep 17 00:00:00 2001
From: etheisen <etheisen@openbsd.org>
Date: Sun, 28 Apr 1996 07:38:22 +0000
Subject: [PATCH] Added dummy mount/umount() syscalls for bogus Linux
 applications that blindly call mount().  These dummy calls always return
 EPERM.  Fixed uncommented NetBSD tag problem encountered when using
 makesyscalls.sh.
