Well as I say - no strong opinions either way here.  It just seems a bit
odd to burden the kernel with an additional fs for such a small user base
when either options exist.

OTOH when we merge a new fs that also has the side-effect of increasing the
active developer base - the maintainers of the fs fix other stuff.  And
I'll do anything to get some acpi bugs fixed ;)

So.. whatever.  I'll keep a look out for v4.
