Thanks for the reminder - I would have forgotten it otherwise.

This never worked correctly in previous Linux releases, right?

My understanding -- possibly incorrect -- of Linus's policy is that the 
-rc cycle should primarily be for regressions.  So I think that the 3.3 
window is the right place for this patch.

But if you can get a special dispensation from the Linux popes, I don't 
have any objection to having it go in earlier ;-)

Anyway, queued here for 3.3.
