Thank you for revisioning while addressing my comments on the previous version!

Maybe because of this, sashiko was unable to review this.
To my understanding, there is no real reason to make this based on damon/next.
And I'd like to get sashiko review for this patch. Could you please rebase
this to latest mm-new and repost for that?

Other than the lack of the sashiko review, this cover letter looks good to me.
Thanks,
