We appear to have some outstanding activity on this quite old patchset.
From my notes:
- An unresponded-to question from Claudia:
https://lkml.kernel.org/r/20230307192421.30ab869c@p-imbrenda
- Hoping for overall review from David
- Another query from Claudia, and a response indicating that a v7 is
in the works.
https://lore.kernel.org/all/20230307194320.79373a26@p-imbrenda/T/#u
- Another unresponded-to review query:
https://lkml.kernel.org/r/20230307195119.745d0b46@p-imbrenda
- Another response indicating that a v7 is coming
https://lkml.kernel.org/r/20230307195313.2e21245a@p-imbrenda
So I think I'll drop the v6 series. Please address all these things in
the next version and let's start over.
