If anyoneîreally cares about this he or she should just kill the uuid
table entirely. We can simple walk a list of mounted xfs filesystems
and check their uuids. The VFS even keeps a list already, which we
probably could use if we are careful.
Bonus points for implementing this in a way so that other filesystems
could share the code.
