Hmm... so, _internal headers are for things which aren't interesting to
other subsystems in the kernel. ie. internal to this particular subsystem,
which is the case here. I understand that _internal may be counter-intuitive
if the reader isn't working in the kernel tree, but am not sure that's a
primary concern in naming source files.

Thanks.
