Since there appears to be only one non-core (for now) fs that needs
this facility it's a bit surprising that it can't be made to be
The old VFS_VPTOFH macro could just return EOPNOTSUP for filesystem
consumers that use it on non-supporting filesystems.
Filesystems that don't need the new VOP version could make use of
a default op that just calls the old style VFS operation.
Not that is has to be done this way, but I'm just saying, there was
little need to kneecap our third party developers. :)
