Thanks for considering trying it out.  I thought it was easy to apply onto any
of the recent branches as long as with -mm's rc1 applied, and I just did it to
Linus's 5.16-rc1 in my uffd-wp rebase:

This commit is here:

It could be that "git rebase" is normally smarter so I didn't notice it's not
applicable directly.

I'll repost a new version soon, please also consider to fetch directly from the
git tree too before I do so.

Thanks,
