Constants

       NVME_NS_FEAT_THIN
                   If set, indicates that the namespace supports thin provisioning. Specifically,
                   the Namespace Capacity reported may be less than the Namespace Size.

       NVME_NS_FEAT_NATOMIC
                   If set, indicates that the fields NAWUN, NAWUPF, and  NACWU  are  defined  for
                   this  namespace  and  should be used by the host for this namespace instead of
                   the AWUN, AWUPF, and ACWU fields in the Identify Controller data structure.

       NVME_NS_FEAT_DULBE
                   If set, indicates that the controller supports the  Deallocated  or  Unwritten
                   Logical Block error for this namespace.

       NVME_NS_FEAT_ID_REUSE
                   If  set,  indicates  that  the value in the NGUID field for this namespace, if
                   non- zero, is never reused by the controller and that the value in  the  EUI64
                   field for this namespace, if non-zero, is never reused by the controller.

       NVME_NS_FEAT_IO_OPT
                   If set, indicates that the fields NPWG, NPWA, NPDG, NPDA, and NOWS are defined
                   for this namespace and should be used by the host for I/O optimization
