Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

147 | To simplify the data structure handling, we actually include the | ||

149 | |||
150 | A driver needs to provide a dev_node_t structure for each device | ||

152 | example, ethernet cards, modems). In other cases, there may be | ||
153 | many actual or logical devices (SCSI adapters, memory cards with | ||
154 | multiple partitions). The dev_node_t structures need to be kept | ||
155 | in a linked list starting at the 'dev' field of a dev_link_t | ||
156 | structure. We allocate them in the card's private data structure, | ||
157 | because they generally shouldn't be allocated dynamically. | ||
158 | |||
159 | In this case, we also provide a flag to indicate if a device is | ||
160 | "stopped" due to a power management event, or card ejection. The | ||
