Of course. There's no way for the app to tell glibc that the app doesn't
care about st_ino, so glibc must assume that glibc needs to return an
accurate st_ino.  The alternative is to return the lower 32 bits of
st_ino, thus causing silent subtle failures in the very small number of
applications which actually do something with st_ino.  This is what
glibc used to do back when I first started tracking the issue.

Yes.
