At first sight this looks astonishingly radical. On further
reflection, it strikes me as radical but elegant. I'll have a little
userland code of my own to change, but less than I thought, and that
much only to deal properly with filesystems >2G on 32-bit machines.
Since I'm unlikely to be doing any of the work, I really don't have a
vote, even if this were a voting situation. Notwithstanding that, I
vote for (3). :-)
