How do I know which patch goes to which branch? Please make it so obvious I can not get it wrong. Remember, I get 1000 emails a day, you don't want me to have to make a judgement call about anything, as I will mess it up :) thanks, greg k-h

I have only sent what I thought is appropriate for 4.18 (cleanup/features will be sent separately): * 5 bug fixes (1-5/7) * 1 update the maintainer list (7/7) * 1 update to the comment to prevent checkpatch from complaining (6/7) If you think any patch is unsuitable to 4.18 - please say which.

Also, please break this up into two different patch series. One for 4.18-final and one for 4.19-rc1. You should always split up bugfixes from new features/cleanups as that is what I have to do when sending them to Linus. thanks, greg k-h
