Do you plan an update to a newer kernel like 5.12-rc3? > Signed-off-by: Lecopzer Chen > Acked-by: Andrey Konovalov > Tested-by: Andrey Konovalov > Tested-by: Ard Biesheuvel You could move these to individual patches rather than the cover letter, assuming that they still stand after the changes you've made. Also note that Andrey K no longer has the @google.com email address if you cc him on future patches (replace it with @gmail.com).
