On your local system. what's the outcome of 'modinfo cifs' ?

Btw - recent debian/ubuntu packages ship versions of the smb/cifs userland
helpers smbmount and smbumount, which are no longer mounting smbfs when
specified. Instead they mount cifs vfs "behind the scenes".
Both are (usually) also called indirectly by the mount/umount programs.
Technically spoken, 'mount -t smbfs ...' is (ususally) calling 
/sbin/mount.smbfs which formerly mounted smbfs - but now cifs vfs instead.
Cheers, Günter
