You'ld have to check the commit history in CVS or SVN to be s= ure. 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=3Drevision&revision=3D223637 AFAIK, that is not a candidate for MFC to stable/8 or earlier, as it modifies KBIs.
