    a) sftp is path based protocol, there's no separate lookup

    b) sftp doesn't transfer st_ino or st_dev, they are both made up on
    the client side

    That is fine. It's clearly a superior sulution when the info is
    available. With sshfs the server simply doesn't care about mounts,
    and so this is basically out of the question.
