svc_xprt_enqueue() can be costly, since it involves selecting and waking up a process. More than one enqueue is done per incoming RPC. For example, svc_data_ready() enqueues, and so does svc_xprt_receive(). Also, if an RPC message requires more than one call to ->recvfrom() to receive it fully, each one of those calls does an enqueue. To get a sense of the average number of transport enqueue operations needed to process an incoming RPC message, re-use the "packets" pool stat. Track the number of complete RPC messages processed by each thread pool.
