Having sent Greg an inappropriate device support patch (for stable)
right smack dab in the middle of this thread, what I can say as a
developer who tends to have to work all over the place in the kernel,
is that deriving the rules is still difficult (as Guenter Roeck has
alluded to in his posts here).

Greg's response to me was direct, informative, and maybe just a little
bit shame-inducing "You know better than that." I know Greg well enough
not to take that personally and I can see him saying that with a smile
on his face, so no complaints there. However, the truth is, I didn't
know better because despite having read the docs, it wasn't clear to
me. Part of the reason there is the language used wasn't clear to me,
specifically "New device IDs and quirks are also accepted". I took
quirks to mean augmenting existing drivers to handle new devices with
subtle changes when in fact it meant something more along the lines of
a couple of lines to add device IDs and existing quirks to a new
device. Greg provided me with example commit IDs which met that
requirement (and perhaps such examples should be added to the docs).

I believe we could improve that documentation to help clarify the
requirements to people that don't work with it everyday. I have offered
to have a look and see what would have made it more clear to me, and I
will do that.

I do believe our processes are becoming a bit fragmented. While every
maintainer certainly needs some autonomy to be able to define how
people work with them in order to maximize their efficiency, the
difference (or lack thereof) between -RC4 and stable wasn't clear to
me, and couldn't be deduced from stable_kernel_rules. Guenter mentioned
some tribal-knowledge associated with /net rules (which I had just
unwittingly violated in the patch mentioned above). I wonder if we
could somehow merge policies where possible, and document those that
should be different in a place where people are likely to find them -
perhaps associated with get_maintainer.pl since anyone submitting
patches should be checking that output anyway.

In summary, better consolidated documentation using language that is
clear to non-subsystem-experts and less tribal knowledge. If people
don't read the documentation that we put in front of their nose....
well, then I suppose we can scold them a bit.
