Hi Kory, all,

The change that introduced this warning introduced a log of such warnings.
Including a lot in the Networking subsystem. (I did not count them.)

So I agree with the point from Sean Christopherson [*] is that if the patch
that introduced the warnings isn't reverted then a more comprehensive
approach is needed to address these warnings.

It was reverted, thankfully. So I assume we treat this patch as 
a normal "include what you need" case and therefore apply.. ?
