Looks good, can you add sample output of:
ndctl list --dimms --health --idle
...so users know what to expect. With that change and addressing
Linda's comment about the temperature multiplier I think we're good to
go.
Also, if you want to add Microsoft-only health attributes we'll need
to add new "valid" flags beyond the current ND_SMART_*_VALID set. If
this goes beyond the current 32 "valid" flags that that
ndctl_cmd_smart_get_flags() returns we might need a new
ndctl_cmd_smart_get_flags2() call that returns an arbitrary bitmap of
valid flags.
We'd also need to move those definitions to an ndctl local header.
Currently where they are defined now in ndctl.h is owned by the
kernel. We can cross this bridge later in a follow-on patch.
