+ * The following few functions deal with caching TellMeAboutYourself calls
+ * that we issued to clients. Why do we do this? Well:
+ *
+ * Q: First, why do we need to issue a TMAY against a client on an incoming new
+ * Rx connection?
+ *
+ * A: We must verify that the incoming Rx connection is the same host that
+ * we have a 'host' structure for. On new calls for existing connections, we
+ * can remember which host corresponds to that connection, but for new
+ * connections, we have no way to find what host it is for, except by looking
+ * up the host by IP address. Since hosts can change IP addresses, we need to
+ * contact the IP address to see if it's the host we think it is.
+ *
+ * Q: Okay, then why cache the results?
+ *
+ * A: The TMAY calls to a single host are serialized, because they are issued
+ * with the host's host->lock held. If we get 4 Rx calls each on new
+ * connections to the same host at the same time, the 1st call will lock the
+ * host, and issue a TMAY. Once that's done, the second call will issue a
+ * TMAY, then the 3rd and then the 4th. However, the 3rd and 4th calls have
+ * been waiting to issue a TMAY since before the 2nd call even _started_ to
+ * issue a TMAY. So, we can just effectively give the results of the 2nd
+ * call's TMAY to the 3rd and 4th, too. Since it is nondeterministic which of
+ * those calls gets to issue a TMAY "first", we can just assume they all got
+ * the same result.
+ *
+ * Note that in the above example, we cannot reuse the results of the 1st TMAY
+ * for the 2nd, 3rd, and 4th calls (we only reuse the results of the 2nd).
+ * This is because by the time the 2nd call starts waiting for the host lock,
+ * it doesn't know how long the 1st TMAY has been running, so the 2nd call
+ * might indeed get a different TMAY result (though this probably would be
+ * extremely rare).
+ *
+ * Anyway, so, if we don't cache the results, we are issuing TMAYs that are
+ * pure overhead. In an environment with clients that create a lot of
+ * connections to a fileserver (keep in mind each new PAG on OpenAFS clients
+ * creates a new connection), this can mean a significant amount of overhead.
+ * So, we use this "TMAY cache" to avoid this overhead for the common case.
