getfh() is for an nfs server, but fhopen(), fhstat(), and fhstatfs() are
not. They were designed as part of the NAStore system, a system for doing
data migration. Also, they were adopted by arla to replace arla-specific
system calls which did the same thing.

What practical problems are there with their use?
