smartd does not run self-tests on NVME devices

[elenril]

I am very happy that 7.4 adds support for self-tests on NVME devices to smartctl, and it indeed works with the two drives in my machine. However, this does not seem to extend to smartd, as it seems to be ignoring these devices when running self-tests.

I have the following line in my smartd.conf:

DEVICESCAN -d removable -s (S/../.././02|L/../15/./03) -n standby -m root -M exec /usr/share/smartmontools/smartd-runner

but have also tried specifying the devices explicitly. smartd does recognize the devices and claims to monitor them (see attached log), just never runs any self-tests (unlike on SATA devices).
