Oh, kernel.org vs github doesn't matter. I'm not actually merging this
yet, I'm just doing a fetch to then easily be able to look at it
locally in different formats.

I tend to like seeing small things in my MUA just because then I don't
switch back-and-forth between reading email and some gitk workflow,
and it is easy to just scan through the series and reply all inthe
MUA.

But when it's some bigger piece, just doing a "git fetch" and then
being able to dissect it locally is really convenient.

Having worked with patches for three decades, I can read diffs in my
sleep - but it's still quite useful to say "give me the patches just
for *this* file" to just see how some specific area changed without
having to look at the other parts.

Or for example, that whole pte_mkwrite -> pte_mkwrite_novma patch is
much denser and more legible with color-coding and the --word-diff.

Anyway, I'm scanning through it right now. No comments yet, I only
just got started.
