39 * Note, fw_device.generation always has to be read before fw_device.node_id.
40 * Use SMP memory barriers to ensure this. Otherwise requests will be sent
41 * to an outdated node_id if the generation was updated in the meantime due
44 * Likewise, fw-core will take care to update .node_id before .generation so
45 * that whenever fw_device.generation is current WRT the actual bus generation,
46 * fw_device.node_id is guaranteed to be current too.
48 * The same applies to fw_device.card->node_id vs. fw_device.generation.
