Some patches for BFQ/block-stable conflict with patches for BFQ-dev/block-mainline.

To use lucjan-kernels smoothly apply ll-reverts before linux-lucjan patch. Otherwise the kernel will not compile.

Enable bfq

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

You can also add this to file 60-schedulers.rules:

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

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

For now, bfq is enabled by default! (since 5.0-lucjan-ll1-rc1.patch and LL-elevator-set-default-scheduler-to-bfq-for-blk-mq.patch)
