That one should be fixed in r280149, sorry about that. For some reason I never hit the triggering condition in testing, but it seems that just about everyone else in the world did. :/ There are a couple locking-related fixes still needed which might trigger a witness warning, they should be fixed soon as well. -- Ian _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
