Depending on how ugly you want to get, you could store lists of
referrers and referents in POSIX xattrs and update them with a mv
wrapper.  You have size limits and race conditions to worry about,
though; current ext4 work should lift the size limits when that lands.
I think the VFS has the tools you need if your lists are small enough:

That's probably less awful than building a parallel database for some
use cases.
