[VERIFICATION BIONIC]

I can modprobe the mq-deadline, kyber and bfq schedulers but it looks like doing a modprobe of the cfq and deadline schedulers doesn't list them as choices in the available schedulers:

# uname -r
4.18.0-1009-azure

# modprobe bfq
# modprobe cfq-iosched
# modprobe mq-deadline
# modprobe kyber-iosched
# modprobe deadline-iosched

# tail /sys/block/sda/queue/scheduler
[none] mq-deadline kyber bfq

I have these 4.18 kernel packages installed:

# dpkg -l | grep 4.18 | grep linux
