I have that in my tree to detect LOR with giant. UMA doesn't often need giant but it may in some cases. This caused problems with the fdesc code before. I'd really like something in witness that says "May acquire giant" or maybe even more generally "May acquire lock x" to detect corner cases. Anyway, I Just forgot to delete this diff when I diffed my tree. It has nothing to do with the buf cache. :-) Cheers, Jeff To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
