    Minimise crref() and add a fastpath for cache hits
    
    Reduce the number of times we cref() unnecessarily, and add a fastpath
    at the beginning of readpage() to handle the cache hit case.
    
    Refactor the Linux implementation of afs_open to provide a directly
    callable version that bypasses the OSI layer.
