Looking at the patch you're applying it looks like NVME disks
are not currently included - was that deliberate?
Yep. BFQ maintainer said:
The rule doesn't consider nvme devices either, but, in this
respect,
I'd agree with testing this change with only single-queue devices
first.
See

I realise considerations may be different for SSDs but SATA SSDs
do seem to be included and the bug explicitly mentions it as being
suitable for SSDs.
If this experiment gives positive results, we can easily extending the
rule to cover more devices.
