There is no "language spec" the kernel adheres to. Even if it did, kernel code is not frozen.

We use compiler extensions of several kinds, for many years. Even discounting those extensions, the kernel is not even conforming to C due to e.g. strict aliasing. I am not sure what you are trying to argue here. But, since you insist: yes, the `fallthrough` attribute is in the current C2x draft.
