I'm not a maintainer but if I was, in that case I would
NAK this since more people wanted the cowfile() definition
than your reflink definition.

If you persist that you are only doing the snapshot
then call it snaplink(2) or something.

The reflink() name makes no sense because all references are
internal to the file system.  There is absolutely no way via
"ls" to determine the reference between the original and new.

With hard links and symlinks you can easily associate them.
