Hi, Thorsten here, the Linux kernel's regression tracker. Top-posting for once, to make this easily accessible to everyone. Does anyone know what happened to below patch? It afaics was meant to fix a regression that made it into 6.6. For details see: https://lore.kernel.org/lkml/87a5v8szhc.fsf@xxxxxxxxx/ https://lore.kernel.org/lkml/ac9d4f7b-c7af-4d21-b0b8-d0f188b94b0f@xxxxxxx/ Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page.
