Here are the stats for the last release cycle: based on 15,383 emails netdev has seen since Dec 15th, over 68 days (226 msgs / day). Roughly 55% of the patches merged had a review tag (4% of which were exclusively from the same email domain as the author). This means an increase of 7% compared to the previous cycle (from 48%). When comparing the stats note the fluctuation in total number of messages (6.2 cycle had roughly 3k more messages). Top 10 reviewers (thr): Top 10 reviewers (msg): 1. [276] Jakub Kicinski 1.

[100] Paul Blakey Vladimir claims the top author spot continuing work on TSN (taprio, mqprio, MAC Merge uAPI and driver support). Stephen Rothwell takes spot number 5, meaning we must have had 27 merge conflicts, lets try to have fewer conflicts going forward...

[ 58] Piergiorgio Beruto Lorenzo, Paul and Oleksij author much more than they review :) Although in all fairness most folks on the list are there due to reving the same series rather than generating a lot of code. Interestingly the flow of semi-automated trivial patches seem to have slowed down significantly (authors of those previously occupied most of the top 5 spots).

As mentioned bots have mostly disappeared in this release cycle, Marvell and Alibaba are the top "net negative" contributors in terms of reviews. Microchip has dropped off the negative list.
