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, -- Peter Xu
