I was under the impression that you had pulled them into your for-next 
branch, and forgot that that would mean probably mean 4.8 at the 
earliest, although looking at your tree now, I notice that the only 
patch from the series there is the first one which fixes a lockdep 
warning, and looking again at the ML is the only one you said you added.

So, taken altogether, the prediction was largely predicated on me being 
significantly absent-minded.
