53 * Note, fw_device.generation always has to be read before fw_device.node_id.
54 * Use SMP memory barriers to ensure this. Otherwise requests will be sent
55 * to an outdated node_id if the generation was updated in the meantime due
56 * to a bus reset.
57 *
58 * Likewise, fw-core will take care to update .node_id before .generation so
59 * that whenever fw_device.generation is current WRT the actual bus generation,
60 * fw_device.node_id is guaranteed to be current too.
61 *

65 * the lifetime of any fw_unit belonging to the fw_device, before device_del()
66 * was called on the last fw_unit. Alternatively, they may be accessed while
67 * holding fw_device_rwsem.
