I'd say BFQ on devices that are not multi-queue, and either none or mq-deadline on devices that are. This is detectable through sysfs. [root@flap ~]# cat /sys/block/nvme0n1/queue/scheduler [none] mq-deadline [root@flap ~]# grep SCSI_MQ /boot/config-4.20.0-0.rc5.git2.1.fc30.x86_64 # CONFIG_SCSI_MQ_DEFAULT is not set I'm not sure why it's not set, it is the default upstream.
