I appreciate your time, and understand you even need to read students’
dissertations. ;-)

I will write it clearly in the cover-letter in the next version, and move
the license changes to 4.19.

Thanks,

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  :)

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.

Thanks,

Again, no blank line between these things.

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.
