Why? Well, why should the routines that call into file systems need to=20

Why? That's the best level for this. Only the file system really knows=20
what's going on. So it's the best place to put the hooks.
Note: to be clear, I think it'd be best if the fileassoc call that says=20
"file is gone" comes from the fs itself as opposed to above it.
