    Looks reasonable, but think xfs_readsb should simply be changed to
    turn all EFSCORRUPTED returns into EINVAL if loud is not set. The
    place that changes the errno value would also be a perfect place to
    comment why we are doing this in the code so that this knowledge doesn't
    get lost.
