 non-swap entries

Hi David, Lorenzo,

Thanks to both of you for the deep dive on this!!!

The code we've been discussing was moved to a new helper by
another patch series[1], so let's call it a day on this
thread and leave it as-is and just review/change the logic
at its new home :)

Thanks a lot!
