I would prefer that as well but that would require an exhaustive search of all existing module event handlers to determine MPSAFE-ness up front. With the mark as MPSAFE method (such as we've used for syscalls) we can mark things MPSAFE (and/or add locking to make them MPSAFE) while doing the exhaustive search and eventually when all are MPSAFE we can remove the flag (which I'm in the process of doing now with the syscall flag) all the while having a functioning system. -- John Baldwin _______________________________________________ cvs-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/cvs-all To unsubscribe, send any mail to "[EMAIL PROTECTED]"
