		Due to the record nature of this interface with a "read all"

		SEEK_CUR is not supported, returning -ESPIPE (invalid seek) to
		errno whenever requested.

		The output format consists of a prefix carrying the syslog

		Description:
		(RO) Report flags indicating various states of a
		papr-pmem NVDIMM device. Each flag maps to a one or
		more bits set in the dimm-health-bitmap retrieved in
		response to H_SCM_HEALTH hcall. The details of the bit
		flags returned in response to this hcall is available
		at 'Documentation/powerpc/papr_hcalls.rst' . Below are
		the flags reported in this sysfs file:

		* "not_armed" : Indicates that NVDIMM contents will not
		survive a power cycle.
		* "flush_fail" : Indicates that NVDIMM contents
		couldn't be flushed during last
		shut-down event.
		* "restore_fail": Indicates that NVDIMM contents
		couldn't be restored during NVDIMM
		initialization.
		* "encrypted" : NVDIMM contents are encrypted.
		* "smart_notify": There is health event for the NVDIMM.
		* "scrubbed" : Indicating that contents of the
		NVDIMM have been scrubbed.
		* "locked" : Indicating that NVDIMM contents cant
		be modified until next power cycle.
