get_swap_bio() question

Hi,

I'm looking at get_swap_bio() in mm/page_io.c and wonder why the result of
map_swap_page() in there is multiplied by (PAGE_SIZE >> 9).  Is it the block
size of 512 B hardcoded?  And if so, is that actually right (I mean, aren't there
any block devices with different block sizes)?
