Function nvme_get_ctrl_telemetry 

pub unsafe extern "C" fn nvme_get_ctrl_telemetry(
    fd: c_int,
    rae: bool,
    log: *mut *mut nvme_telemetry_log,
    da: nvme_telemetry_da,
    size: *mut usize,
) -> c_int

nvme_get_ctrl_telemetry() - Get controller telemetry log @fd: File descriptor of nvme device @rae: Retain asynchronous events @log: On success, set to the value of the allocated and retrieved log. @da: Log page data area, valid values: &enum nvme_telemetry_da @size: Ptr to the telemetry log size, so it can be returned

The total size allocated can be calculated as: (nvme_telemetry_log da size + 1) * NVME_LOG_TELEM_BLOCK_SIZE.

Return: The nvme command status if a response was received (see &enum nvme_status_field) or -1 with errno set otherwise.
