But bio_end_sector() kind of sounds that it will calculate to the last sector of bio. So I thought of it more as bio_last_sector() and not the sector which is next to the last sector. Will it make sense to introduce bio_last_sector() and use +1 everywhere. Or may be we need a better name. Can't think of one though.
