Hmmm. Seems to be a general problem whether building a shared library,
or a kernel module.
I.e. as soon as I have more than one source file in my lib or module, I
suddenly have to make some functions not static, and they become visible
Is there no way to compile and link a.c and b.c so that only specific
entry points are visible before statically linking ab.o with the rest of
the kernel or making ab.o into a kernel module.
