even for dynamically linking including non-GPL code is not white but
already dark grey.

There are no "persons responsible for defending the kernel GPL", there
are just a few hundreds or thousands copyright holders of the kernel,
and each of them has the right to sue you if he thinks you distribute
something that violates his copyright. Jurisdiction and applicable
copyright law depends on things like where the copyright holder lives
and where you distribute it.
