so it seems to be something in the cifs kernel client doing this. Can 
you somewhere post a network trace that covers this?

@Steve: do you have some fallback logig in the client that is triggered 
if a rename fails with STATUS_ACCESS_DENIED and then removed the 
(existing) rename destination?

Thanks!
