Hi Jens, bio_add_hw_page currently fails miserably when trying to add larger contiguous ranges than support by the underlying hardware, a it always adds everything or nothing. That isn't really a problem yet as there are no callers that actually pass anything where off + len doesn't fit in a single page, but I've been working on code that will, which immediately tripped it.
