struct nvme_io_args - Arguments for NVMe I/O commands @slba: Starting logical block @storage_tag: This filed specifies Variable Sized Expected Logical Block Storage Tag (ELBST) or Logical Block Storage Tag (LBST) @result: The command completion result from CQE dword0 @data: Pointer to user address of the data buffer @metadata: Pointer to user address of the metadata buffer @args_size: Size of &struct nvme_io_args @fd: File descriptor of nvme device @timeout: Timeout in ms @nsid: Namespace ID @data_len: Length of user buffer, @data, in bytes @metadata_len:Length of user buffer, @metadata, in bytes @nlb: Number of logical blocks to send (0’s based value) @control: Command control flags, see &enum nvme_io_control_flags. @apptag: This field specifies the Application Tag Mask expected value. Used only if the namespace is formatted to use end-to-end protection information. @appmask: This field specifies the Application Tag expected value. Used only if the namespace is formatted to use end-to-end protection information. @reftag: This field specifies the variable sized Expected Initial Logical Block Reference Tag (EILBRT) or Initial Logical Block Reference Tag (ILBRT). Used only if the namespace is formatted to use end-to-end protection information. @dspec: Directive specific value @dsm: Data set management attributes, see &enum nvme_io_dsm_flags @rsvd1: Reserved @reftag_u64: This field specifies the variable sized Expected Initial Logical Block Reference Tag (EILBRT) or Initial Logical Block Reference Tag (ILBRT). It is the 8 byte version required for enhanced protection information. Used only if the namespace is formatted to use end-to-end protection information. @sts: Storage tag size in bits, set by namespace Extended LBA Format @pif: Protection information format, determines how variable sized storage_tag and reftag are put into dwords 2, 3, and 14. Set by namespace Extended LBA Format.
