Yes, basically replace "git am" with "git fetch" if the cover letter has
a line that looks like it's produced by "git request-pull".

Well, I wouldn't mind (I send pull requests to Peter anyway, and I'd
certainly want s390x pull requests addressed to me as well).

We could use both (subject prefix and To:/Cc:) for a
belt-and-suspenders approach.

Cool.

Would a certain formatting be helpful for patchew as well? Or do you
plan to parse the cover letter to hopefully find the output of git
request-pull and get the correct base from that?

The only thing I currently require is that the body text
contains the appropriate magic words and that it goes to
qemu-devel in to or cc.

All this time I thought it was /already/ required to cc Peter on
pull requests !

Yeah, but that would not be too hard.  There are only about 40
maintainers, and if anybody misses the news they would notice fairly
quickly. :)

BTW, Fam and I are also planning to improve Patchew so that it is better
at detecting pull requests and especially merged pull requests.

Thanks,

It would require existing submaintainers to change their process,
though -- currently not all pull requests are to/cc me.

What about just requiring you to be in the "To" or "Cc" fields?  That
works pretty well for Linux.

Yes, "PULL SUBSYSTEM " looks reasonable.

The block folks are already doing this, so we should just
formalize what they're doing at the moment I guess. From my point
of view as long as there's something I can easily filter
in/out in the email body or subject so I don't get confused
(and which doesn't require me to update my filters every time
a new subsystem switches to using submaintainer pulls!)
I don't mind about the rest of it. Maybe a subject line with
'PULL SUBSYSTEM s390x' (ditto block, etc etc) ?
