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.
