Yike thanks very much!

If it's at all possible for you to confirm this happens on Linus's tree
just to be super super sure (again I totally expect this) then that'd be
amazing.

I ask because we have another thread which bisected a problem to this
commit which we didn't think was the cause and seemed actually to be the
result of something else fiddling around with things it shouldn't so just
want to entirely rule that out (a fix was applied to Linus's tree for
that).
