    tipc: Convert node object array to a hash table · 672d99e1
    Allan Stephens authored
    Replaces the dynamically allocated array of pointers to the cluster's
    node objects with a static hash table. Hash collisions are resolved
    using chaining, with a typical hash chain having only a single node,
    to avoid degrading performance during processing of incoming packets.
    The conversion to a hash table reduces the memory requirements for
    TIPC's node table to approximately the same size it had prior to
    the previous commit.
    In addition to the hash table itself, TIPC now also maintains a
    linked list for the node objects, sorted by ascending network address.
    This list allows TIPC to continue sending responses to user space
    applications that request node and link information in sorted order.
    The list also improves performance when name table update messages are
    sent by making it easier to identify the nodes that must be notified.
