The Darwin kernel includes HFS and HFS+ support. I assume the interface to
the rest of the kernel is too different to port it easily, and the license
Apple has it under wouldn't allow it to become part of the official kernel.
However, I'm pretty sure it would be possible to distribute source for a
kernel module based on the darwin HFS code. That would be "good enough" for
a lot of people, since the source stays open if you do that. You don't have
freedom to do stuff with it, but that shouldn't be too much of a problem for
a driver for a specialized filesystem. Still, Free would be better. I
don't remember how bad the apple license is, but they don't require your
house and first-born child or anything :)
