![]() After switching data directions, deadline always starts the next batch from the lowest-sector request. This gives excessive deadline expiries and large latency and throughput disparity between high- and low-sector requests; an order of magnitude in some tests. This patch changes the batching behaviour so new batches start from the request whose expiry is earliest.
