Yes, but the fact that you pass an invalid fd in the first place is not
normal.  The reason for returning an error in this case is to tell the
application that the data it wanted to flush has not been.  The whole
point of eatmydata is to let the application think it has been flushed.

Also, why does anyone give a damn about not getting EBADFD?  You should
never see this in practice anyhow.
