Like I said in v2, I don't object the change if you would like to include this patch to 4.17, so if you are sure this patch is safe and want to commit it, feel free to add: Release-acked-by: Henry Wang <[email protected]> Since we also need to commit: "[PATCH for-4.17] SUPPORT.md: Define support lifetime" so from my side I am no problem. Julien might have different opinion though, if Julien object the change I would like to respect his opinion and leave this patch uncommitted. Kind regards, Henry > > Jan
