The merge window has now begun, this set is rather large and Linus said
that he will be particularly strict about applying patches late:

https://lore.kernel.org/all/CAHk-=wj_HcgFZNyZHTLJ7qC2613zphKDtLh6ndciwopZRfH0aQ@mail.gmail.com/

So let's defer this for after 6.2-rc1 is cut. Feed free to switch to
RFC postings if you want to keep revising the set and make review
progress during the merge window.
