NAME

       enum  nvme_id_ns_flbas  -  This  field  indicates  the LBA data size & metadata size combination that the
       namespace has been formatted with

SYNOPSIS

       enum nvme_id_ns_flbas {
           NVME_NS_FLBAS_LOWER_MASK ,
           NVME_NS_FLBAS_META_EXT ,
           NVME_NS_FLBAS_HIGHER_MASK

       };

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.
