*
* RPC client per-operation statistics provide latency and retry
* information about each type of RPC procedure in a given RPC program.
* These statistics are not for detailed problem diagnosis, but simply
* to indicate whether the problem is local or remote.
*
* These counters are not meant to be human-readable, but are meant to be
* 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.
