140 | A dev_link_t structure has fields for most things that are needed | |

143 | 'priv' pointer in a dev_link_t structure can be used to point to | |
144 | a device-specific private data structure, like this. | |
145 | ||
146 | To simplify the data structure handling, we actually include the | |
147 | dev_link_t structure in the device's private data structure. | |
148 | ||
149 | A driver needs to provide a dev_node_t structure for each device | |
150 | on a card. In some cases, there is only one device per card (for | |
151 | example, ethernet cards, modems). In other cases, there may be | |
152 | many actual or logical devices (SCSI adapters, memory cards with | |
153 | multiple partitions). The dev_node_t structures need to be kept | |
154 | in a linked list starting at the 'dev' field of a dev_link_t | |
155 | structure. We allocate them in the card's private data structure, | |
156 | because they generally shouldn't be allocated dynamically. | |
157 | ||
158 | In this case, we also provide a flag to indicate if a device is | |
159 | "stopped" due to a power management event, or card ejection. The | |
160 | device IO routines can use a flag like this to throttle IO to a | |
161 | card that is not ready to accept it. | |
