Oops. This is what one gets by pushing at 2am. I fixed that one up (still didn't even build as I'm in the middle of a conference). Also it's actually the reverse test2 is just the revert test1 has one more bugfix. So I'm inclined to push test2 out to linux-next for now, and will add test1 later if it fares well. Mike, your testing is very much appreciated! -- MST
