Stubs for this code were added under the CONFIG_CIFS_EXPERIMENTAL tag in 2007, but were never completed. The upshot -- anyone who turns on CONFIG_CIFS_EXPERIMENTAL gets a filesystem that pretends to allow exporting via nfsd. Trying to actually use it will just get you an error once nfsd tries to walk into the directory. Remove this code since it's unfinished. We can reintroduce it once someone spends time on it and makes it usable.
