This was sort of my impression. I started working on it myself, but I'd rather have somebody that knows what the hell they're doing to begin with do it. :-) In particular, it didn't look very complete, and I would have to figure out what's been added to bdevsw/etc.... Not that that's HARD, but it would be easier for somebody already familiar.... It did look a lot easier than some of the the alternatives. :-) I had been looking at some of the Sprite code for RAID, but wasn't too sure what sort of shape that was in, and of course it might have been a lot of work to port? If you choose to start working on this, I would appreciate it if you would keep me up to date, a little? Thanks... ;-) ...
