This enables the block layer to send us a full plug list of requests that need submitting. The block layer guarantees that they all belong to the same queue, but we do have to check the hardware queue mapping for each request. If errors are encountered, leave them in the passed in list. Then the block layer will handle them individually. This is good for about a 4% improvement in peak performance, taking us from 9.6M to 10M IOPS/core.
