Hi Jens,

Request queues are run asynchronously if BLK_MQ_F_BLOCKING has been set. This
results in suboptimal performance. This patch series improves performance if
BLK_MQ_F_BLOCKING has been set by running request queues synchronously
whenever possible.

Please consider this patch series for the next merge window.

Thanks,

Bart.

  scsi: Remove a blk_mq_run_hw_queues() call
