	Does this mean someone may be free to write wrappers that block
	ENOSYS, execute statfs calls, and fall back to ostatfs calls
	(translating 64->32 bit values as best as possible, like the kernel
	does) returning the new statfs?  Obviously, this would just be to
	add a safety window for the transition period and to be removed
	before a -RELEASE.

	 Opinions expressed are my own.               \,,,,,,,,,,,,,,,,,,,,,,\

The above would certainly be possible. If this were a more heavily
used interface (like say stat), it would be a useful exercise. But
I do not feel it is really necessary for statfs. However, I am not
going to object if someone wants to go through the exercise of 
implementing your suggestion.
