How about rearranging this series that these patches comes first and could be backported? Well - as far as I know 6+7+8 can get applied independently (and you will need 6 as otherwise you would need to apply at least 8 in 2 places). The one observation that I have made is that when applying those against 4.14 you needed some more patches that have gone in since 4.14 to apply cleanly. Martin
