We should control the RPC rate from single client to guarantee it is fair for all clients as much as possible. Otherwise a powerful and busy client maybe occupies most of services on server(s), and then causes other client(s) starvation, that is unfair.</p> <p>Currently, Lustre has some RPC rate control, like inflight lookup/getattr RPC count is limited by the 'cl_max_rpcs_in_flight'. But the existing RPC rate control mechanism is not complete, for example, the inflight OST side lock enqueue RPC count is unlimited.</p> <p>We want to implement more general RPC rate control framework, and try to cover operations as much as possible (if need rate control), including the inflight OST side lock enqueue RPC.</p> LU-765
