Constants

       NVME_SMART_CRIT_SPARE
                   If set, then the available spare capacity has fallen below the threshold.

       NVME_SMART_CRIT_TEMPERATURE
                   If  set, then a temperature is either greater than or equal to an over temperature threshold;
                   or less than or equal to an under temperature threshold.

       NVME_SMART_CRIT_DEGRADED
                   If set, then the NVM subsystem reliability has been degraded due to significant media related
                   errors or any internal error that degrades NVM subsystem reliability.

       NVME_SMART_CRIT_MEDIA
                   If set, then all of the media has been placed in read only mode. The controller shall not set
                   this bit if the read-only condition on the media is  a  result  of  a  change  in  the  write
                   protection state of a namespace.

       NVME_SMART_CRIT_VOLATILE_MEMORY
                   If  set,  then  the volatile memory backup device has failed. This field is only valid if the
                   controller has a volatile memory backup solution.

       NVME_SMART_CRIT_PMR_RO
                   If set, then the Persistent Memory Region has become read-only or unreliable.
