The scheme you've implemented can apply fine to a .ko file after it's made.
They are just .o's really. It is presumably faster to do one step per
final .ko rather than many tiny ones (per source file).
That might be a benefit to doing it all at the end for vmlinux too. I
think the best way would be to have a vmlinux.o that we actually use in the
link, rather than just analyzing and discarding. Then you can just do your
existing hack on vmlinux.o before it's linked into vmlinux.
Thanks,
Roland
