The original version is correct.  If you have 4k fsblocks and a
zerorange request for 8GB - 2 bytes starting at 4097, you'll have to
actually zero 4097-8191 and 8589930496 - 8589934591.  (Almost) one block
each, at each end.

That said, "one block at each end" conveys that adquately in modern day
English usage and people think I'm old fashioned even for uttering the
first version. ;)

(Old fashioned being 1960s :P)
