.SH NAME
enum nvme_smart_crit \- Critical Warning
.SH SYNOPSIS
enum nvme_smart_crit {
.br
.BI " NVME_SMART_CRIT_SPARE"
,
.br
.br
.BI " NVME_SMART_CRIT_TEMPERATURE"
,
.br
.br
.BI " NVME_SMART_CRIT_DEGRADED"

};
.SH Constants
.IP "NVME_SMART_CRIT_SPARE" 12
If set, then the available spare capacity has fallen
below the threshold.
.IP "NVME_SMART_CRIT_TEMPERATURE" 12
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.
.IP "NVME_SMART_CRIT_DEGRADED" 12
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.
.IP "NVME_SMART_CRIT_MEDIA" 12
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.
.IP "NVME_SMART_CRIT_VOLATILE_MEMORY" 12
If set, then the volatile memory backup
device has failed. This field is only valid if the
controller has a volatile memory backup solution.
.IP "NVME_SMART_CRIT_PMR_RO" 12
If set, then the Persistent Memory Region has become
read-only or unreliable.
