About a cycle ago, Arnd and i played around with this idea. The
Ethernet PHY subsystem is W=1 clean, and most of he network stack
is. But keeping it clean is not so easy, when developers do sometimes
add new warnings, since they have no idea the code is W=1 clean.

You are also not the only one asking for such a feature. RDMA also
asked recently.

Arnd, do you plan to push the patches?
