Chuck Lever 552bf22528 xprtrdma: Use new CQ API for RPC-over-RDMA client receive CQs ... Calling ib_poll_cq() to sort through WCs during a completion is a common pattern amongst RDMA consumers. Since commit 14d3a3b249 ("IB: add a proper completion queue abstraction"), WC sorting can be handled by the IB core. By converting to this new API, xprtrdma is made a better neighbor to other RDMA consumers, as it allows the core to schedule the delivery of completions more fairly amongst all active consumers. Because each ib_cqe carries a pointer to a completion method, the core can now post its own operations on a consumer's QP, and handle the completions itself, without changes to the consumer. xprtrdma's reply processing is already handled in a work queue, but there is some initial order-dependent processing that is done in the soft IRQ context before a work item is scheduled. IB_POLL_SOFTIRQ is a direct replacement for the current xprtrdma receive code path.
