Thanks Mpe for explaining and apologies Rob as I initially didnt get the
point you made. I wrongly assumed that since the patch can only be
applied on top of commit fee3ff99bc67 hence fixes should point to
fee3ff99bc67.

I have sent out a v2 with the updated Fixes tag and also changes as
suggested by Mpe and Rob at
