Or the stable team can just pick these up? Please see https://www.kernel.org/doc/html/v6.11/process/stable-kernel-rule= s.html. If Option 2 can't work (because of conflicts), please follow Option 3 (https://www.kernel.org/doc/html/v6.11/process/stable-kernel-rules.html#opt= ion-3). Just explain the background and link to this thread in a cover letter and mention it's your first time. Greg didn't bite me when I fumbled my way around it :) (greg, please correct me if I'm talking rubbish) thanks, sam
