The rr_base field is currently the buffer where RPC replies land. An RPC/RDMA reply header lands in this buffer. In some cases an RPC reply header also lands in this buffer, just after the RPC/RDMA header. The inline threshold is an agreed-on size limit for RDMA SEND operations that pass from server and client. The sum of the RPC/RDMA reply header size and the RPC reply header size must be less than this threshold. The largest RDMA RECV that the client should have to handle is the size of the inline threshold. The receive buffer should thus be the size of the inline threshold, and not related to RPCRDMA_MAX_SEGS. RPC replies received via RDMA WRITE (long replies) are caught in rq_rcv_buf, which is the second half of the RPC send buffer. Ie, such replies are not involved in any way with rr_base.
