You'ld have to check the commit history in CVS or SVN to be sure. In fact, the last import listed as such in the CVS history was from OpenBSD 4.1 but that was around 2007 when FreeBSD was on version 6.x -- long time ago. There's been plenty of updates since (which, IIRC, made the FreeBSD code pretty much equivalent to what is in OpenBSD 4.2), but no wholesale reimport until about 2 months ago, when OpenBSD 4.5 code was imported into head. http://svnweb.freebsd.org/base?view=revision&revision=223637 AFAIK, that is not a candidate for MFC to stable/8 or earlier, as it modifies KBIs.
