Yes, for sure we need to improve the workflow. After the return from KS,
I found ~400 patches/pull requests on my queue. I'm working hard to get rid
of that backlog, but still there are ~270 patches/pull requests on my
queue today.

The thing is that patches come on a high rate at the ML, and there's no
obvious way to discover what patches are just the normal patch review
discussions (e. g. RFC) and what are real patches.

To make things worse, we have nowadays 494 drivers. A very few of those
have an entry at MAINTAINERS, or a maintainer that care enough about
his drivers to handle patches sent to the mailing list (even the trivial
ones).

Due to the missing MAINTAINERS entries, all patches go through the ML directly,
instead of going through the driver maintainer.

So, I need to manually review every single email that looks to have a patch
inside, typically forwarding it to the driver maintainer, when it exists,
handling them myself otherwise.

I'm counting with our discussions at the Barcelona's mini-summit in order
to be able to get fresh ideas and discuss some alternatives to improve
the patch workflow, but there are several things that could be done already,
like the ones you've proposed, and keeping the MAINTAINERS file updated.

Regards,
Mauro
