oplock breaks

In implementing oplock code in the Linux cifs vfs I noticed that Win2K
sends a UID of zero (but non-zero FID and TID) on the oplock break from the
server ... this implies that the space of valid fids is not related to the
UID. Thus if I thought that it were possible to do more than 64K open
instances to a particular Windows server the fids it generates are either
unique across a particular tid or unique across a particular tid across a
particular TCP connection? and the tids that the server generates are also
unrelated to the UID ...
