The relevant part of the patch series (08/10) has been (or will be) reverted by Andy to resolve the problem for the moment (as per my earlier email). The issue that part 08/10 was aiming to fix will be addressed in a more complete way in a follow up patch series from Michael in due course as explained in my Reviewed-by comment. Regards jonathan
