Thanks for the effort and the persistence! I understand the frustration
with AI review and discontinuous feedback, unfortunately the volume of
patches on the ML makes such sloops more frequent than before.

I merged this version, addressing an hopefully trivial conflict. @Breno:
a second pair of eyes on the resolution would be appreciated.

@Alice: please follow-up on the possible gso_segs overflow ASAP.

Thanks,

Paolo
