+ * RPC client per-operation statistics provide latency and retry

+ * These statistics are not for detailed problem diagnosis, but simply
+ * to indicate whether the problem is local or remote.

+ * integrated into system monitoring tools such as "sar" and "iostat". As
+ * such, the counters are sampled by the tools over time, and are never
+ * zeroed after a file system is mounted. Moving averages can be computed
+ * by the tools by taking the difference between two instantaneous samples
+ * and dividing that by the time between the samples.
+ *
+ * The counters are maintained in a single array per RPC client, indexed
+ * by procedure number. There is no need to maintain separate counter
+ * arrays per-CPU because these counters are always modified behind locks.
