Regarding the review under https://netdev-ai.bots.linux.dev/sashiko/#/patchset/20260508154314.12817-1-sw%40simonwunderlich.de The fix for this existing problem is planned for the second net PR - splitted due to the amount of patches. Besides this split, was not included in this one because I am waiting for the author to submit the v2 with my change request (to also fix the second occurrence of the invalid `atomic_dec_and_test`): https://patchwork.open-mesh.org/project/b.a.t.m.a.n./patch/df73e607bda0c84b22d64d80f8ac887190242baf.1778118303.git.rakuk...@gmail.com/ Regards, Sven
