I think it's more common in the target code to put the sector_size and hw_block_size on different lines. It would be nicest to tab them over to line with the opening "(" but I guess the hw_block_size line would be over 80, so something like this is ok: dev->dev_attrib.hw_max_sectors = mult_frac(queue_max_hw_sectors(q), SECTOR_SIZE, dev->dev_attrib.hw_block_size); > dev->dev_attrib.hw_queue_depth = q->nr_requests; > > if (target_configure_unmap_from_queue(&dev->dev_attrib, bd))
