Ingo,

the build failure had got addressed by a different patch already,
albeit that patch seems far from ideal to me. I.e. I still think cleanup
along the lines of the patch here is desirable, but I need to submit
one that actually builds (the build failure the test robot encountered
is a direct result of the clash between the two patches). I have that
patch ready, but didn't want to submit before I got around to test it
with 3.18-rc.
