Unfortunately I don't have a spare machine handy, but I ran a kernel compile job in our lab and at least I can confirm that it applies + compiles fine (i386 target on amd64, RELENG_9_1, options UNIONFS static included on a heavy-nodevice-over-GENERIC kernel). Thanks, -Harry P.S.: I'll have a nice testing machine vacant soon, so if no one else has time to test, I can come back in about 2 weeks with results. But that's far too late for 9.1-RELEASE I guess.
