So basically, all I need to do to satisfy your request is to add fixes
branch that I push to that is pushed after it passes my tests (and not
the urgent branch that is still being tested and may have bugs) and
then have that be added to linux-next?

Now I have been batching changes and not send a pull request right
after my tests pass. I've been sending a pull request at most now once
a week. So I could have this branch hold the code that's already been
tested.
