    kernel - Fix clustered read bug
    
    * cluster_read() was improperly reducing the 'maxra' variable when
      handling the read-ahead mark, creating a degenerate situation which
      would cause only the first few burst reads from a file to cluster,
      and the remainder to read-ahead but not cluster.
