Hi Heiner!
This series silently conflicts with Daniel's changes. I wasn't clear
whether the conclusion here:
https://lore.kernel.org/all/1261b3d5-3e09-4dd6-8645-fd546cbdce62@gmail.com/
is that we shouldn't remove the define or Daniel's changes are good
to go in.. Could y'all spell out for me what you expect?
