I'm not sure that NUMA balancing is something you'll be able to do in a module - I
am pretty sure that not all the infrastructure you'll need is accessible from a module.
If you're ending up tossing EXPORT_SYMBOL() all over the place, making your own
code a module isn't going to help.

Plus, one of the big reasons to use modules while developing is so you can
just insmod/rmmod and iterate testing without needing to reboot.  I doubt
that you'll be able to remain constrained to balancing techniques that
support an rmmod - the kernel doesn't have much infrastructure to
defend against race conditions against module removal other than the
reference count against the module itself.

Derp.  That was from a previous draft and not removed - I think it was the first line
scrolled out of sight in the mail edit buffer. :)
