Enable bfq-mq

For now, you can use sudo tee /sys/block/sda/queue/scheduler <<< bfq-mq to enable "bfq-mq".

You can also add this to your udev rules:

# Non-rotational disks
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="bfq-mq"
# Rotational disks
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="1", ATTR{queue/scheduler}="bfq-mq"

and run a command sudo udevadm control --reload && sudo udevadm trigger
