Hi Jens, The two patches in this patch series change the default I/O scheduler of request queues created by the loop driver from 'mq-deadline' into 'none'. Please consider these two patches for inclusion in the Linux kernel. Thanks, Bart. Changes compared to v2: - Dropped the patch that makes the loop driver queue depth configurable via a kernel module parameter. - Added a q->tag_set test in patch 1/2. Although I'm not sure this test is still needed after Christoph's latest queue creation rework, it doesn't harm. Changes compared to v1: - Introduced BLK_MQ_F_NO_SCHED_BY_DEFAULT and use it in the loop driver. - Removed BLK_MQ_F_NO_SCHED again from the loop driver. Bart Van Assche (2): blk-mq: Introduce the BLK_MQ_F_NO_SCHED_BY_DEFAULT flag loop: Select I/O scheduler 'none' from inside add_disk() block/elevator.c | 3 +++ drivers/block/loop.c | 3 ++- include/linux/blk-mq.h | 6 ++++++ 3 files changed, 11 insertions(+), 1 deletion(-)
