This looks good.

Vs. merge logistics: I'm expecting some other changes in that area as per
discussion with megasas (IIRC) folks. So I'd like to apply that myself
right after -rc1 and provide it to you as a single commit to pull from so
we can avoid collisions in next and the merge window.

Thanks,
