This should not be needed at all, as it make absolutely no sense.

Is this really needed?  Now that the code is in the kernel tree,
shouldn't you be tracking this based on kernel release version (like 90%
of the drivers are tracked), or is there some requirement for a version
number?

And what decides when this number is changed?  What does it "mean"?
What is it tracking?
