>Subject: [PATCH] media_harmony VFS module: Add and build by default.
>
> - Supersedes previous patch.
> - Added various fixes for fake mtime functionality.
> - Now requires lp_cache_locked_write_times patch (bug 8912).
> - Removed various xattr functions to comply with recent VFS changes.
> - Changed SMB_STRUCT_DIR to DIR and SMB_STRUCT_DIRENT to struct dirent to comply with recent VFS changes.
> - Added manpage.
> - Added sample trigger_avid_update.py script.

>+ * Media Harmony is a Samba VFS module that allows multiple AVID
>+ * clients to share media. Each client sees their own copy of the
>+ * AVID msmMMOB.mdb and msmFMID.pmr files and Creating directories.
>+ *
>+ * Add this module to the vfs objects option in your Samba share
>+ * configuration.
>+ * eg.
>+ *
>+ *   [avid_win]
>+ *	path = /video
>+ *	vfs objects = media_harmony
>+ *	...
>+ *
>+ * It is recommended that you separate out Samba shares for Mac
>+ * and Windows clients, and add the following options to the shares
>+ * for Windows clients  (NOTE: replace @ with *):
>+ *
>+ *	veto files = /.DS_Store/._@/.Trash@/.Spotlight@/.hidden/.hotfiles@/.vol/
>+ *	delete veto files = yes
>+ *
>+ * This prevents hidden files from Mac clients interfering with Windows
>+ * clients. If you find any more problem hidden files then add them to
>+ * the list.
>+ *
>+ *
>+ * Andrew Klaassen, 2012-03-14
>+ * To prevent Avid clients from interrupting each other (via Avid's habit
>+ * of launching a database refresh whenever it notices an mtime update
>+ * on media directories, i.e. whenever one editor adds new material to a
>+ * shared share), I've added code that causes stat information for anything
>+ * directly under "Avid MediaFile/MXF" to be taken from
>+ * dirname_clientaddr_clientuser if it exists.  These files ~aren't~
>+ * hidden, unlike the client-suffixed database files.
>+ *
>+ * For example, stat information for
>+ *	Avid MediaFiles/MXF/1
>+ * will come from
>+ *	Avid MediaFiles/MXF/1_192.168.1.10_dave
>+ * for dave working on 192.168.1.10, but will come from
>+ * 	Avid MediaFile/MXF/1_192.168.1.11_susan
>+ * for susan working on 192.168.1.11.  If those alternate
>+ * directories don't exist, the user will get the actual directory's stat
>+ * info.  When an editor wants to force a database refresh, they update
>+ * the mtime on "their" file.  This will cause Avid
>+ * on that client to see an updated mtime for "Avid MediaFiles/MXF/1",
>+ * which will trigger an Avid database refresh just for that editor.
>+ *
>+ *
>+ * Notes:
>+ * - This module is designed to work with AVID editing applications that
>+ * look in the Avid MediaFiles or OMFI MediaFiles directory for media.
>+ * It is not designed to work as expected in all circumstances for
>+ * general use. For example: it is possibly to open client specific
>+ * files such as msmMMOB.mdb_192.168.1.10_userx even though is doesn't
>+ * show up in a directory listing.
