What if the xstat() and struct xstat eventually becomes what userspace uses as
stat() (as a wrapper) and struct stat (if such a thing is possible with glibc
versioning)?  Do older programs that think they're using stat() and don't know
about the extra fields available expect to see a useful value in st_ino?
