From d296c774c5981baa863c697782dba1b6280d632e Mon Sep 17 00:00:00 2001
From: Jeremy Allison <jra@samba.org>
Date: Fri, 7 Aug 2009 12:38:31 -0700
Subject: [PATCH] Move the checks for null timestamps down below the VFS_NTIMES
 layer (as it's done in onefs). This simplifies greatly the code in
 smb_set_file_time() w.r.t. changenotify messages. Jeremy.
