Thanks for the info. I agree, in this case the idea is not worth the
effort.

Ideally, I would like all call instructions patched up to point to
correct destinations. An ELF image is a first approximation to this
(in the user space it will have calls to PLT, but I have already dealt
with those). A kernel module's .o file is harder -- even intra-module
calls have zero offsets.

Totally agree. I will implement proper support for loadable modules,
but wanted to do a quick test. After all, it is just a research
project :)

Thanks,
Alex
