* XXX CSM Reported on samba-technical 12/7/2002
*
* There is a case for which server(s) return
* ERRnoaccess but should return ERRdiskfull: When
* the offset for a write is exactly the server
* file size limit then Samba (at least) thinks
* the reason for zero bytes having been written
* must have been "access denied" from the local
* filesystem. This cannot be easily worked
* around since the server behaviour is
* indistinguishable from actual access denied.
* An incomplete workaround: attempt a 2 byte write
* from "offset-1". (That may require reading at
* offset-1 first.) The flaw is that reading or
* writing at offset-1 could cause an
* unrelated error (due to a byte range lock
* for instance) and we can't presume the
* order servers check errors in.
