There is probably nothing wrong with the snapshots.  This is a bug in

linked multiple times and the parent pointer (i.e. directory) was
recycled and is now a file

Interesting... do the ZPL files in ZFS keep pointers to parents?

How in the COW transactiveness could the parent directory be
removed, and not the pointer to it from the files inside it?
Is this possible in current ZFS, or could this be a leftover
in the pool from its history with older releases?
