Re: no version magic, tainting kernel.

Thanks for your answers!

I did not compile my module with a kernel Makefile, I used the very small and
simple one attatched to this mail. So it seems I miss something when the
module is linked and I have to know what I have to link to the module or
which header-file I have to include...

For me it seems link I have to link the init/vermagic.c file to my module, but
how would this be possible if only the kernel includes were available??
I think only these should be needed to compile a module...
