From af8a691db11a5072865f8b03fd1cbd3aab5cb6d7 Mon Sep 17 00:00:00 2001
From: Jeremy Allison <jra@samba.org>
Date: Fri, 8 Jul 2005 04:51:27 +0000
Subject: r8219: Merge the new open code from HEAD to 3.0. Haven't yet run the
 torture tests on this as it's very late NY time (just wanted to get this work
 into the tree). I'll test this over the weekend.... Jerry - in looking at the
 difference between the two trees there seem to be some printing/ntprinting.c
 and registry changes we might want to examine to try keep in sync. Jeremy.
 (This used to be commit c7fe18761e2c753afbffd3a78abff46472a9b8eb)
