From f80a526546c68468b3c24b84a7a62088d2e86260 Mon Sep 17 00:00:00 2001
From: Tim Potter <tpot@samba.org>
Date: Wed, 24 Oct 2001 00:45:41 +0000
Subject: Renamed global_vfs_ops to default_vfs_ops and made static.

Make a copy of the default ops structure rather than following a pointer.

This fixes the audit VFS example module!
(This used to be commit 91ab6f75d9e6820a13fe3034a5f100ae170ad164)
