I hope that makes review easier. See https://lore.kernel.org/all/20221108194139.57604-1-torvalds@linux-foundation.org for the series if you weren't mentioned and are interested. Oh, and because I decided to just use the email in this thread as the reference and cover letter, it turns out that this all confuses 'b4', because it actually walks up the whole thread all the way to the original 13-patch series by PeterZ that started this whole discussion. I've seen that before with other peoples patch series, but now that it happened to my own, I'm cc'ing Konstantine here too to see if there's some magic for b4 to say "look, I pointed you to a msg-id that is clearly a new series, don't walk all the way up and then take patches from a completely different one. Oh well. I guess I should just have not been lazy and done a cover-letter and a whole new thread. My bad. Konstantin, please help me look like less of a tool? Linus
