Before cleanup:
enum ib_poll_context poll_ctx;
if (nvme_rdma_poll_queue(queue)) {
poll_ctx = IB_POLL_DIRECT;
queue->ib_cq = ib_alloc_cq(ibdev, queue, queue->cq_size,
comp_vector, poll_ctx);
} else {
poll_ctx = IB_POLL_SOFTIRQ;
queue->ib_cq = ib_cq_pool_get(ibdev, queue->cq_size,
comp_vector, poll_ctx);
}
After cleanup:
if (nvme_rdma_poll_queue(queue))
queue->ib_cq = ib_alloc_cq(ibdev, queue, queue->cq_size,
comp_vector, IB_POLL_DIRECT);
else
queue->ib_cq = ib_cq_pool_get(ibdev, queue->cq_size,
comp_vector, IB_POLL_SOFTIRQ);
IB_POLL_SOFTIRQ/IB_POLL_SOFTIRQ gets used directly in function, this
seems more accessible.
