Yes, please.

That would work if the others would be doing the same. Unfortunately, other
usual developers don't do that: they send all patches under discussions as
"PATCH", making really hard to track what's ready for maintainer's review 
and what isn't. As not-so-frequent contributors (trivial fixes people; users
submitting their bug fix patches; first time contributors) send their patch
as "PATCH". Those patches aren't typically picked by driver maintainers,
so the task of reviewing them is, unfortunately, typically done only by
me.

Yes, please post them as [RFC PATCH].

Maybe the patches that are about to be sent though a pull request could
use something like [RFC FINAL] or [PATCH FINAL], but maybe doing that
would be just overkill.

Well, if people don't comment the RFC patches, they should not be complaining
when it gets merged.

Thinking about that, by not having a "non-RFC" final patch series may actually
improve the process at long term, as people will look with another eyes for
the RFC ones.

Yes.

See: 
	http://patchwork.linuxtv.org/patch/13763/

This is pretty much the same case of 13659, except that the patch was a
RFC (not tagged as such), and it was wrong. The correct one is:

	http://patchwork.linuxtv.org/patch/13790/

Without tagging them differently, I don't have any way to know what are
ready for merge, and what wasn't.

Anyway, I'm open to ideas on how to handle it better, especially when it helps
to allow handling patches on uniform way, without needing to apply different
procedures for each driver maintainer.

Mauro
