1547 | * bio merging done at NVME page size boundary calling kernel API | |
1548 | * blk_queue_virt_boundary inside slave_config. | |
1549 | * Still there is possibility of IO coming with holes to driver because of | |
1550 | * IO merging done by IO scheduler. | |
1551 | * | |
1552 | * With SCSI BLK MQ enabled, there will be no IO with holes as there is no | |
1553 | * IO scheduling so no IO merging. | |
1554 | * | |
1555 | * With SCSI BLK MQ disabled, IO scheduler may attempt to merge IOs and | |
1556 | * then sending IOs with holes. | |
1557 | * | |
1558 | * Though driver can request block layer to disable IO merging by calling- | |
1559 | * queue_flag_set_unlocked(QUEUE_FLAG_NOMERGES, sdev->request_queue) but | |
1560 | * user may tune sysfs parameter- nomerges again to 0 or 1. | |
1561 | * | |
1562 | * If in future IO scheduling is enabled with SCSI BLK MQ, | |
