Is this possible with the current libnetfs? libnetfs is doing that
port creation stuff alone without user-defined callbacks.

netfs_S_dir_lookup() wants netfs_attempt_lookup() to lookup the
node. Then, a new protid/peropen structure is created inside
netfs_S_dir_lookup() via netfs_make_{protid,peropen}() - in
netfs_make_protid() the new port for the user is created with
ports_create_port().
