    NFSv4.1: Ensure that the client tracks the server target_highest_slotid · 464ee9f9
    Trond Myklebust authored
    Dynamic slot allocation in NFSv4.1 depends on the client being able to
    track the server's target value for the highest slotid in the
    slot table.  See the reference in Section 2.10.6.1 of RFC5661.
    
    To avoid ordering problems in the case where 2 SEQUENCE replies contain
    conflicting updates to this target value, we also introduce a generation
    counter, to track whether or not an RPC containing a SEQUENCE operation
    was launched before or after the last update.
    
    Also rename the nfs4_slot_table target_max_slots field to
    'target_highest_slotid' to avoid confusion with a slot
    table size or number of slots.
