From 4085fb08fdd936212d9f3bbc9ded660dd3332786 Mon Sep 17 00:00:00 2001
From: Tim Potter <tpot@samba.org>
Date: Mon, 5 Apr 1999 05:19:34 +0000
Subject: Fix incorrect conversion of fd_attempt_open() calls to
 vfs_ops.open().

Use VFS I/O for fd_attempt_open() and check_access_allowed_for_current_user().
(This used to be commit abf31ca66f3dab1b8bd7772f83e736e41afb4b1e)
