I too agree with the principle of the patch.  There's no reason to
limit this quantity to 16 bits.

I can't see any particular reason.

Did you test it?  There are four combinations to check:

new application/new kernel
old application/new kernel  (to test symbol versioning)
new application/old kernel  (test translation of old structure to new)
old application/old kernel  (this should Just Work if the above cases work)
			    (but of course you should still check it :-) )
