[ANN] netdev development stats for 6.7

[ANN] netdev development stats for 6.7

[Jakub Kicinski]

Hi!

General stats
-------------

The cycle started on August 29th and ended on Oct 31st, 1 day shorter
than previous one, due to the timing of our PR.

We have seen total of 14243 messages on the list (226 / day) which 
is 17% lower than the (very busy) 6.6 cycle. The number of commits
directly applied by netdev maintainers dropped by 13% to 19 commits 
a day, close to our long term average.

There was a fluctuation in the number of participants. While the number
of people "reviewing" (replying in threads) remained constant (around
410) the number of people exclusively starting threads ("authors"?)
decreased by 40 (344 -> 306).

Fraction of changes with Review/Ack tags has dropped again to 58%
(counting all tags) and 50% (counting tags from different company
than the author).

Justin has posted the most individual patches, replacing the use of
unsafe string APIs throughout the drivers. Jiri jumps into top 5
with his devlink and YNL work. David H posted a few series for iov
and network file systems (somewhat netdev-adjacent). Dmitry contributed
the TCP Auth Option support. Herve worked on a HDLC framer for QMC.

The biggest change in the company statistics is the disappearance
of Corigine. Simon is now employed at Red Hat, giving Red Hat the
#1 spot with quite some margin.

With Corigine dropping out, Enfabrica (David Ahern) and Broadcom
(Florian Fainelli) ascend to the top #7.

A few things worth noting in the "community score" metrics.

Intel moved from the "negative" to the "positive" side (at #13, so not
high enough to make the "top"). Shout out to Jake, Wojciech and Przemek
for their review work! This move may have been helped slightly by the
lower volume of Intel patches and external contributions to Intel
drivers. So please do not rest on your laurels :)

nVidia makes the opposite switch and ironically takes negative spot #2,
the exact spot previously occupied by Intel. Jiri's efforts are not
enough to counter balance the flow of patches there :(

Arista is likely a blip as Dmitry had to repost his work a few times.

Bootlin and Pengutronix return to the same (negative) positions they
held in 6.5 cycles. It may be the time to carve out more review time
for folks working at those companies.

I just noticed this stats report from Simon. Thanks for your work and
sharing. I want to know if there is a way to bind my personal email
with my company so my review could increase my company's score :)
I think there are some other company developers who use their own email
also curious.

Thanks and Best Regards
Hangbin

Jonathan Corbet <corbet@lwn.net> maintains a list of email addresses
to organisations mapping. Let him know who you work for and the next
cycle you should count to your company.

Thanks for asking, the company association is my least favorite part 
of this work, and you gave me an excuse to rant about it :)

Yes, unfortunately I do not have access to that list. The LWN list was
compiled with some assurances of the list not being shared. Jon / Greg
understandably did not want to send me the list and break that promise.

So telling Jon won't help me.

Now, CNCF has a similar setup: https://github.com/cncf/gitdm
and they do share their database. So I use that, plus my local hacky
mapping. Unfortunately the CNCF DB is not very up to date for kernel
folks.

Hangbin, according to CNCF you're at Red Hat, which seems sane, and
that's how I count you :)

Now the rant.

Unfortunately I can't handle creating a company/developer DB myself,
because of GDPR etc. I work for a company which takes personal
information very, very seriously.

I brought creating a public DB up at Linux Foundation TAB meetings,
but after some poking there's no movement.

To add insult to injury, if you watch past the end of the recent
(excellent) talk from Jon - https://lwn.net/Articles/949647/ you will
see Jim Zemlin pop up on the stage after Jon finishes, and you will
hear him tout the great "analytics tools" that Linux Foundation
has been working. I think he's talking about this:
https://insights.lfx.linuxfoundation.org/projects/korg/dashboard

It would be great if Linux Foundation helped the community with the
developer/company DB, which is ACTUALLY USEFUL BEFORE WASTING TIME ON
SOME WEB STUFF THAT DOESN'T WORK FOR THE KERNEL.

This makes me so angry.

Thanks for this info. Glad to know my email and company are mapping correctly.

I personally agree Linux Foundation should maintain a developer/company DB.
The developer could submit their information on a voluntary basis, instead of
letting some tools search the website and collect data.

Thanks
