To be clear Christoph, your saying you'd like the NQN in the prefix of the dmesg?

E.g.:

root> echo "round-robin" > /sys/class/nvme-subsystem/nvme-subsys11/iopolicy
[Thu Jun 24 11:44:20 2024] subsysnqn nqn.1992-08.com.netapp:sn.2b82d9b13bb211ee8744d039ea989119:subsystem.SS104a iopolicy 
changed from queue-depth to round-robin.

Correct?
