I got 6 warnings booting my machine after pulling back from Linus
(which included your patches in net for the first time).
And that's not including the XPS and the virtio warning.

This sounds too close to saying that "it's okay for -rc1 to be broken".
Why were your changes not in linux-next for a month before the merge
window? :(

We will not be merging a refactoring series into net to silence an
arguably over-eager warning. We need a minimal fix, Guo Ren's patches
seem to miss the mark so I reckon the best use of everyone's time is 
to just drop the exposing patch and retry in -next 🤷
