Well, bio means "block I/O" to me these days and we already have a lot of names which point to that as the logical prefix (biodone() being just one of them). As for going the struct uio route, yes we may want to consider that at some point. I think it makes sense to do this relatively simple (but tedious) divorce of the io aspect of struct buf first, before we change the semantics of the actual io handling. -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
