  "message": "Deadline iosched: Fix batching fairness\n\nAfter switching data directions, deadline always starts the next batch\nfrom the lowest-sector request.  This gives excessive deadline expiries\nand large latency and throughput disparity between high- and low-sector\nrequests; an order of magnitude in some tests.\n\nThis patch changes the batching behaviour so new batches start from the\nrequest whose expiry is earliest.\n\nSigned-off-by: Aaron Carroll \u003caaronc@gelato.unsw.edu.au\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n",
