On our side, we prefer to use the general LTS kernel release instead of a customized kernel, in case we will not align on major fixes down the road. So would like to know if there is any plan to backport these patches and if so, what is the timeline? Thanks a lot again for any advice. Easy: use 5.10. It's LTS and has all the patches you care about. -- Thanks, Sasha
