Are you sure it is ok for 4.9? If so, Florian, can you >provide a backported version of it? My objection to taking documentation patches is either that we take all of them, or we take none. If we take only select documentation fixes it makes a frankenstein Documentation/ directory that might cause more harm than benefit. Let's say I'm looking for netfilter documentation on 4.19, can I trust linux-4.19.y or do I look upstream? Right now I know I have to look upstream, but if we tell people it's okay to trust the linux-4.19.y docs then we might be causing harm to our users when some fixes were backported but corresponding documentation fixes weren't. -- Thanks, Sasha
