I have just seen this on 6.8.0-22-generic on a libvirt host running serveral k8s instances in KVM. Their drivers are backed by ZFS.
I just switched them to cache=writeback for disks, that might trigger this issue. It happened when they were idle but at a time (8AM) when I suspect some crons ran.
This message just happened again when I was deleting the VMs (virsh destroy) and their disks (zfs destroy).
