I think we are talking past each other. This is what I've been suggesting since my first message, but suggested was a political problem when going to make the necessary VOP_ADVLOCK interface changes. It's also one of the patches I put up a long time ago, and which have been updated to FreeBSD 4.5 by Andrey. He could just take Andrey's code, but if it isn't committed back to FreeBSD, he would have compatability issues. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
