Functional changes look good to me, thank you.
I've made a couple minor formatting corrections in the interest of time. In

spell checker in your $EDITOR for commit messages. Using git am to apply your
own patches would also have caught the whitespace error.

Queued to testing, I'll push to for-next tomorrow(ish), which should give us
