Nope, I'm fine with both solutions.

Agreed.

Cool.

I'm perfectly fine with that.

I use git notes to do that: each time I apply a patch using pwclient,
it adds a note containing the patchwork id, then, I have a pre-push
hook that scan all the commits that are being pushed on my nand/next
branch and mark the new ones as Accepted in patchwork.

I can provide those scripts if you want, but this means it has to be
done on the client side, because notes are discarded when you push
things to a remote.

Well, it all depends on the number of fixes we have. But if we all have
permissions to push to the mtd tree, then we can just create a fixes
branch where the sub-subsystem maintainers can easily push their fixes
and the release owner will then send a PR to Linus before the next -rc.

Thanks.
