In theory this means that using nanotime instead of getnanotime in the KTR_LOCK and/or KTR_WITNESS cases shouldn't recurse anymore, and in fact, it works fine on the alpha, but on x86 I still get weird double fault panics (I assume from exhausting the stack) and haven't been able to get a useful traceback or anything else to figure out where and why it is breaking, so I've left the hack to use getnanotime in for now. -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
