I don't think that works anymore with new glibcs. At any rate smbwrapper, which did cifs client access using this method, can no longer be supported. If I remember correctly Ulrich thinks this is not a supported interface so he removed it.
Doing it in kernel space is not all that hard. There are several incomplete implementations.
