Actually I think you just make one up and advertise it widely.

This won't work for code which must build without dependencies on AFS,
of which might be built on a non-AFS machine and executed on an
AFS-client machine (ie for rpm/deb packaging).
The question is "[on Linux], how can my code reliably determine if a
file is stored in AFS without introducing a build-time dependency on
AFS headers/libraries into my code".
That question has a reasonable answer for SMB, Coda, and NFS; I think
it would be unfortunate if it didn't have a reasonable answer for AFS.

Today (TransarcAFS + OpenAFS<=1.4.x).
I have faith that the people doing byte-locking will come up with an
elegant solution for querying locking capabilities in 1.5 and future
releases. I'm mostly worried about what's already out there.
