It's just that the 1st RFC series was posted ~6 months ago and the major things
should be mostly the same since then (we've got a few patches merged; but
mostly for the sake of dependencies of other projects):
https://lore.kernel.org/lkml/20210115170907.24498-1-peterx@redhat.com/
So I start to doubt whether I should ask you for help (after bothering at least
Mike and Hugh already :), as I have very little confidence that this series
will be reviewed thoroughly in the near future if I do nothing.
But I definitely agree with you, it's still relatively large changeset with not
so much review done. Let's keep it there for some more time, then.
Thanks,
