Yeah, I do know it. I think FreeBSD reinventing what SGI did is stupid. As soon as you get rid of the copy as the issue the VM maps/unmaps become the issue. So they are inching closer to the next problem. Take a look at Stephen Tweedies kio bufs, that's better. You can read a little about them at ftp.bitmover.com://pub/splice.ps, that's where they came from. -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
