I was asked for it by Bernd Schubert for userspace NFS servers and FUSE -
maybe he can say what he wants it for.

I also have a note that Jeremy Allison asked for it, but I can't find where or
why, so that might be an error.

It looks like FreeBSD do have an st_gen field in their stat struct, but it's
only filled in for root.  Maybe I could do something like that?
