Well, this isn't a normal patch series as I took the work from Tzvetomir
back from 2021, and started massaging them. I wanted to keep Tzvetomir's
original authorship even though he's not working on it, so I just applied
his patches as-is and then added patches on top of them, to denote what I
did and what he did.

This is why I never modified the first 5 patches of this series, except for
subject lines and change logs.
