It would be nice if there would be way if the file system would get a

Well, if we cannot agree on that, file system with a custom protocol at
least can detect from 0 to SSIZE_MAX and then reset metadata. I'm not
sure if this would work for pNFS, though.
splice() does not create new files. What you appear to be asking for
lies way outside the scope of that system call interface.
Sorry I know, definitely outside the scope of splice, but in the context
of offloaded file copies. So the question is, what is the best way to
address/discuss that?
Thanks,
