    apars.html
    
    Benefits of the solution:
    Fixed the code by providing the new config option

    at the first level cache fileset, readdir optimization is
    disabled and new files are fetched from the home during the
    readdir and lookup.
    
    Work around:
    None
    
    Problem trigger:
    AFM cascading relationship with AFM+COS fileset.
