I didn't mean it's evil. I just mean it's complicated and potentially
confusing because the result of bmap needs to modified by the number of
blocks per sector to get the right value to pass to bio_submit. Maybe you're
more experienced in these things than me, so it will be simple for you, but
it took a while for me to get right.
