[cifs-protocol] Excel timestamp client side-caching request

   We are still working on identifying the issue.  It seems that when Excel tries to send SET_INFO when closing the file, CSC thinks ,for some reason, that the object is in disconnected offline state and any update to the file is just applied to the CSC local cache.  That is why the SMB Transact2 request is not really sent over the wire.  It looks like that it is timing related as I have much smaller chance to capture the condition if it is running under debugger.

   I will be on vacation next week until Friday.   Nick and Edgar will continue working on the issue.  If you have any information or requests, please let us know.  We will also let you know as soon as we get the root cause on the issue.

Great ! I'm in the process of adding real
create timestamps with full Windows semantics
to the Samba code, so let me know if that's the
issue and I should have some new code later this week :-).

Thanks a *lot* for the help !
