Message-ID: <20251002171032.75263b18@kernel.org> Date: Thu, 2 Oct 2025 17:10:32 -0700 From: Jakub Kicinski <kuba@...nel.org> To: netdev@...r.kernel.org, netdev-driver-reviewers@...r.kernel.org Subject: [ANN] netdev development stats for 6.18 Intro ----- As is tradition here are the development statistics based on mailing list traffic on netdev@...r. These stats are somewhat like LWN stats: https://lwn.net/Articles/1004998/ but more focused on mailing list participation. And by participation we mean reviewing code more than producing patches. In particular "review score" tries to capture the balance between reviewing other people's code vs posting patches. It's roughly number of patches reviewed minus number of patches posted. Those who post more than they review will have a negative score. Previous 3 reports: - for 6.15: https://lore.kernel.org/20250326140948.18a7da36@kernel.org - for 6.16: https://lore.kernel.org/20250529144354.4ca86c77@kernel.org - for 6.17: https://lore.kernel.org/20250728160647.6d0bb258@kernel.org General stats ------------- The 6.18 release was very similar in size to 6.17 for the overall kernel, only -0.3% change in the number of patches queued in linux-next when the merge window opened. For netdev 6.18 was +4% larger in terms of commits merged by core maintainers than 6.17 (which in turn was 3% larger than 6.16). We have seen -3% fewer messages on the list (previous delta was also negative: -1%). Average number of revisions of a patchset decreased by -2%. Testing ------- Proportion of test commits went up by 3% (from 8% to 11% of all commits touching the selftests directory). This is mostly due to efforts of a handful of people, the number of unique contributors to selftest unfortunately went down from 44 to 41. Contributions to selftests: 1 [ 41] Jakub Kicinski 2 [ 20] Kuniyuki Iwashima 3 [ 18] Petr Machata 4 [ 16] Matthieu Baerts 5 [ 13] Ido Schimmel 6 [ 7] Hangbin Liu 7 [ 4] Geliang Tang 8 [ 3] Stanislav Fomichev 9 [ 3] Eric Dumazet 10 [ 3] Dimitri Daskalakis Kuniyuki added a solid chunk of packetdrill tests for TCP Fast Open. Petr cleaned up bash helpers and their use of defer constructs. Metthieu worked on MPTCP tests, and Ido on routing tests. I should mention that the stats only cover work applied by core networking maintainers, work done by trees which send us PRs (Netfilter for instance) does not show up here.

Reviewing various PHY / phylink and embedded networking patches, when he's not busy untangling stmmac :) Vadim continues to review PTP but increasingly also other driver patches. Aleksandr focuses on driver reviews, similarly to Paul Menzel who specifically reviews Intel driver patches. The list doesn't cover the less frequent reviews, but all review work is appreciated! Thank you all!

Fan Gong hinic3 driver. Alok sends a lot of fixes and improvements to random code. One could speculate what technology lays behind those patches but the patches are generally solid :) Laura Nao resends a 27 patch series for MediaTek clock drivers, which is of moderate relevance to netdev, but stats are stats. The remaining names should be familiar.

Broadcom ranking gets pretty negative due to multiple revisions the patches for their new driver are going. Meta (very narrowly) interrupts Red Hat's period of domination across the rankings. -- Code: https://github.com/kuba-moo/ml-stat Raw output: https://netdev.bots.linux.dev/static/nipa/stats-6.18/stdout
