[BUG] smartctl_device_bytes_written not present while data_units_written is present un smartctl

Hello there,

I have read this topic about and issue I have.
Apparently this is solved, but it's not working

I have several NVMe drivers in a machine, the output for, for example, nvme4 is the following:

I am using the latest version of the exporter:

Shouldn't this be solved by this PR?

[k0ste]

Yes it should. This code is not released yet. But may be, when some guy with merge button, merge PR #235

[achetronic]

Yes it should. This code is not released yet. But may be, when some guy with merge button, merge PR #235

Who do we have to invoke? :) I think this is not the most used exporter but super useful and needed in some scenarios
