Why isn't gcc fixed instead? The whole "extern inline" thing was
documented to work the way it did, this gcc breakage is annoying, and
I refuse tp apply patches that imply that it is a bug in the kernel
when it's the compiler that messes up.

So it's not "broken extern inline usage". It's a broken compiler
changing things. Again.
