For example: mtx_assert(&scp->mtx, MA_OWNED) will panic if the mutex scp->mtx is not held. Note that like KASSERT(), mtx_assert()'s are only triggered in the INVARIANTS case. -- 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
