    Is all the information needed available in the VFS layer, or do we need
    to capture metadata at the NFSv4 layer as well, to do it right?  Or
    should we just make sure to coordinate with the NFSv4 team to ensure that
    they keep the info we need around?

    Sorry, it *did* sort of follow, when your first posting wasn't clear, and
    made it sound almost like we didn't need to worry about hooking files if
    they happened to live on NFSv4....
