You all have read my "what kernel should I pick" guide, right? > Can I take this to mean that this patch series is not allowed to go into the > stable kernel? That is correct. Use a newer kernel, it's much better overall. Only reason you should be stuck on 4.19 at this point in time is if you have an SoC with millions of out-of-tree lines added to it (making a Linux-like system), or you are an "enterprise" distro and you are paying for support for them. Or you are using Debian, they know what they are doing there :) thanks, greg k-h
