Patch 4/8 was not acked. I was about to push a new version in which I fix the scenario that Jeremy mentioned. Would you like me to push that as a separate patch on top of this series, or should I push a new version of this series?
All the other patches will be the same.

Will do!
Thank you, Ionela.
