Comment # 4 on bug 1223460 from ted chang

# 3. For "real" multiqueue devices, the kernel defaults to no IO scheduling
# Uncomment this (and select your scheduler) if you need an IO scheduler for
them
TEST=="%S%p/mq/1", ATTR{queue/scheduler}="kyber", GOTO="scheduler_end"

# 4. BFQ scheduler for every device (uncomment if you need ionice or blk-cgroup
features)
# ATTR{queue/scheduler}="bfq", GOTO="scheduler_end"

# 5. mq-deadline is the kernel default for devices with just one hardware queue
# ATTR{queue/scheduler}="mq-deadline"
