From a770caed0ff66ddc2d63ac83d20f4cd7fcc2caf5 Mon Sep 17 00:00:00 2001
From: Jeremy Allison <jra@samba.org>
Date: Tue, 17 Nov 2009 14:55:02 -0800
Subject: Remove "store create time" code, cause create time to be stored in
 the "user.DOSATTRIB" EA. From the docs: In Samba 3.5.0 and above the
 "user.DOSATTRIB" extended attribute has been extended to store the create
 time for a file as well as the DOS attributes. This is done in a backwards
 compatible way so files created by Samba 3.5.0 and above can still have the
 DOS attribute read from this extended attribute by earlier versions of Samba,
 but they will not be able to read the create time stored there. Storing the
 create time separately from the normal filesystem meta-data allows Samba to
 faithfully reproduce NTFS semantics on top of a POSIX filesystem. Passes make
 test but will need more testing. Jeremy.
