fs/bio.c - Hardcoded sector size ?

From: Roger Gammans

In bio_endio() there is the follow line:-

bio->bi_sector += (bytes_done >> 9);

and there is a similiar line assuming a 512byte sector in
__bio_add_page() .

Is this a bug as the the actual block size should be available
from bio->bi_bdev->bd_block_size surely - or is some clever code
where all block devices have to translate back to 512 byte sectors
for bio s.
