Bugger, I should be getting at least warnings when compiling this but I don't.
This is because I don't have CONFIG_LBD enabled. However, the %ld and %d

the other format specifiers should be rq->nr_sectors: %lu, rq->current_nr_sectors: %u.

Would you like to redo your patch and add a proper comment ontop?
