I really detest the iaranges "name", it's horribly illegible. If you want to stick with the ia thing, then disk_register_ia_ranges() would be a lot better (though still horrible, imho, just less so). Same goes for blk-iaranges, we really need to come up with something more descriptive here. -- Jens Axboe
