The !CONFIG_OF stubs aren't static so if multiple files include the
header with this configuration then the linker will see multiple
definitions of the stubs.

Did you actually try to compile this?

If you're going to mark this stuff static, you gotta mark that
shit inline too.

I'll fix this up, but test your changes please.

Yup, and the kernel did actually build.

I'm afraid I missed all those in among the other warnings in net/, sorry
(I needed to do a full rebuild as it was a config change to fix up the
underlying error and I always build with sparse enabled which generates
a bunch of warnings in net/).
