This woried me, as I don't recall anyone notifying me of it. Then I saw your revert, and I noticed that all you really need to resolve this is commit id ec95d35a6bd0047f05fe8a21e6c52f8bb418da55 to be added to the tree. I'll go queue that one up for the next .32-stable tree. So all should be resolved now, right? thanks, greg k-h
