What is interesting, and is why I started collecting this information
years ago, is keeping track of our rate-of-change, the number of new
developers we have contributing, and the number of different companies
and how many of them are contributing. All of those numbers are good to
watch to see how well as a community we are doing.
So far, all of those numbers are going up, which is good. If they ever
stop dropping, I will get worried.
These numbers, and stats, are also good for getting other companies to
get involved in kernel development. I've used them for many years to
point out that they need to get involved, and in one noticable case
(Intel), it has made a huge difference. Other cases (Amazon and
Motorola), it hasn't helped out at all.
They also show what areas of the kernel are under major change and
churn, which is interesting to see for some people who don't pay that
much attention to our community (2 years ago the x86 rework was obvious,
and this year the ARM and SoC work is obvious).

Companies do do that. You also see companies "hiding" their
contributions from the stats as they don't want to show up on the radar
for odd reasons (Qualcomm is one example of this, they spread their
contributions around 3 different companies for "misguided" legal
Microsoft was an interesting example of a company that ended up doing a
lot of work for just one set of drivers, and ended up showing high in
the stats because of that. That provided a great example of a company
that no one had ever thought would contribute, was doing so (the local
Seattle paper's headline read, "Is Cancer Cured?" which was so funny to
me and pissed so many locals off.)
And yes, some companies try to "game" the numbers, but it's really hard
to do this given how much real work is being done by people, and how
obvious it is when it happens. So far I haven't seen anyone succeed in
doing this, but they might have been so good that I didn't notice.
And as always, of course statistics lie, we all know this, but sometimes
they can be helpful for your cause :)
