16 The Reservation Report command returns a Reservation Status data
17 structure to host memory that describes the registration and
18 reservation status of a namespace.
19 The size of the Reservation Status data structure is a function of the
21 number of controllers in the NVM Subsystem that are associated with
22 hosts that are registrants of the namespace (i.e., there is a
23 Registered Controller data structure for each such controller).

26 -n <nsid>, --namespace-id=<nsid>
27 Retrieve the reservation report structure for the given nsid. This
28 is required for the character devices, or overrides the block nsid
29 if given.
30 -d <num-dwords>, --numd=<num-dwords>
32 Specify the number of Dwords of the Reservation Status structure to
33 transfer. Defaults to 4k.
34 -c <cdw11>, --cdw11=<cdw11>
36 The value for command dword 11. Setting bit 0 specifies that the
37 controller returns the Extended Data Structure.
38 -b, --raw-binary
40 Print the raw buffer to stdout. Structure is not parsed by program.
