I agree. The incorrect (or at the very least incomplete and confusing)
claims in bug #201721 made me think it was a regression from older
versions. As it turns out that this isn't the case, my request to
revert 4abb951b73ff0a8a979113ef185651aa3c8da19b from stable kernel
series was incorrect. I apologize for the noise and ask Greg to undo
the revert.

Thanks,
