I think I was retaining that order.  I though someone who knows ther 
server side of the code would confirm either way that the setaddr_unix 
was either correct or broken.  At the moment the driver works so the 
only disadvantage is if there is a trunc at the same time as another 
property change (which may not be possible?) they will be done with 2 
calls instead of the one.

Does this apply to samba servers?  You posted some comment about a 
problem that only applies to windows servers.

No, they are the same.  I did not get any response from the last message 
so I sent them again.

I also have a new patch now for the redhat 2.4.9 kernel but it is not 
fully tested yet.
