AFS has supported full-file locks for many years, but doesn't support
byte-range locking (or, rather, byte-range locks that do not cover the
entire file are only enforced on the local system). In other words, it
basically supports flock and not fcntl, but it will convert fcntl locks
that cover the entire file into the lock type it does understand.
