Subject: [ANN] netdev development stats for 6.7
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).

No surprises in the top 6. Kees takes #7, helping to review string op
safety and __conted_by patches. Wojciech enters the ranking at #15.
Thanks for all the review work, folks!

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.
