| 112 | many actual or logical devices (SCSI adapters, memory cards with |
| 113 | multiple partitions). The dev_node_t structures need to be kept |

| 115 | structure. We allocate them in the card's private data structure, |
| 116 | because they generally shouldn't be allocated dynamically. |
| 117 | In this case, we also provide a flag to indicate if a device is |
| 118 | "stopped" due to a power management event, or card ejection. The |
| 119 | device IO routines can use a flag like this to throttle IO to a |
