Hi, For virtio block device, actually there is no a hard limit for max request size, and virtio_blk driver set -1 to blk_queue_max_hw_sectors(q, -1U);. But it doesn't work, because there is a default upper limitation BLK_DEF_MAX_SECTORS (1280 sectors). So this series want to add a new helper blk_queue_max_hw_sectors_no_limit to set a proper max reqeust size. Weiping Zhang (2): blk-setting:
