DESCRIPTION
-----------
For the NVMe device given, sends a namespace management command to create
the namespace with the requested settings. On success, the namespace
identifier assigned by the controller is returned.

The <device> parameter is mandatory and may be either the NVMe character
device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

OPTIONS
-------
-s::
--nsze::
	The namespace size.

-c::
--ncap::
	The namespace capacity.

-f::
--flbas::
	The namespace formatted logical block size setting.
	Conflicts with --block-size argument.

-d::
--dps::
	The data protection settings.

-m::
--nmic::
	Namespace multipath and sharing capabilities.

-a::
--anagrp-id::
	ANA Group Identifier. If this value is 0h specifies
	that the controller determines the value to use

-i <nvmsetid>::
--nvmset-id=<nvmsetid>::
	This field specifies the identifier of the NVM Set.

-y <command_set_identifier>::
--csi=<command_set_identifier>::
	This field specifies the identifier of command set.
	if not issued, NVM Command Set will be selected.

-l <lbstm>::
--lbstm=<lbstm>::
	Logical Block Storage Tag Mask for end-to-end protection.

-b::
--block-size::
	Target block size the new namespace should be formatted as. Potential FLBAS
  values will be values will be scanned and the lowest numbered will be
  selected for the create-ns operation. Conflicts with --flbas argument.

-S::
--nsze-si::
	The namespace size (NSZE) in standard SI units.
	The value SI suffixed is divided by the namespace LBA size to set as NSZE.
	If the value not suffixed it is set as same with the nsze option.

-C::
--ncap-si::
	The namespace capacity (NCAP) in standard SI units.
	The value SI suffixed is divided by the namespace LBA size to set as NCAP.
	If the value not suffixed it is set as same with the ncap option.
