Heh :)  At first I was just going to correlate with st_ino users to cut
it down, but then I learned that glibc will actually give you an
EOVERFLOW if, say st_ino overflows, even if you were only going to check
st_mode.  :(  So pretty much everything needs fixing.

(FWIW I gathered statfs/statvfs calls, too...)
