Constants

NVME_NS_FLBAS_LOWER_MASK
    Mask to get the index of one of the supported LBA Formats's least significant 4bits indicated in :c:type:`struct nvme_id_ns <nvme_id_ns>`.lbaf.

NVME_NS_FLBAS_META_EXT
    Applicable only if format contains metadata. If this bit is set, indicates that the metadata is transferred at the end of the data LBA, creating an extended data LBA. If cleared, indicates that all of the metadata for a command is transferred as a separate contiguous buffer of data.

NVME_NS_FLBAS_HIGHER_MASK
    Mask to get the index of one of the supported LBA Formats's most significant 2bits indicated in :c:type:`struct nvme_id_ns <nvme_id_ns>`.lbaf.
