Hi Daniel,

I must confess to knowing little or nothing about what SMART requires.
If smartctl would benefit from having an NVMe-specific driver then it'd
be great if somebody worked on that.  If the nvme-scsi module needs a
couple of small enhancements to make the existing smartctl work properly,
then by all means let's add them.  You can see nvme-scsi does translate
LOG_PAGE_TEMPERATURE_PAGE and LOG_PAGE_INFORMATIONAL_EXCEPTIONS_PAGE
already, and does so by requesting the SMART page from the NVMe device.
Is there more that is needed for smartctl's purposes?
