    afs: Implement VL server rotation · 0a5143f2
    David Howells authored
    Track VL servers as independent entities rather than lumping all their
    addresses together into one set and implement server-level rotation by:
    
     (1) Add the concept of a VL server list, where each server has its own
         separate address list.  This code is similar to the FS server list.
    
     (2) Use the DNS resolver to retrieve a set of servers and their associated
         addresses, ports, preference and weight ratings.
    
     (3) In the case of a legacy DNS resolver or an address list given directly
         through /proc/net/afs/cells, create a list containing just a dummy
         server record and attach all the addresses to that.
    
     (4) Implement a simple rotation policy, for the moment ignoring the
         priorities and weights assigned to the servers.
    
     (5) Show the address list through /proc/net/afs/<cell>/vlservers.  This
         also displays the source and status of the data as indicated by the
         upcall.
