| 596 | * hci_conn_get() and hci_conn_put() are used to control the life-time of an |
| 597 | * "hci_conn" object. They do not guarantee that the hci_conn object is running, |
| 598 | * working or anything else. They just guarantee that the object is available |
| 599 | * and can be dereferenced. So you can use its locks, local variables and any |
| 600 | * other constant data. |
| 601 | * Before accessing runtime data, you _must_ lock the object and then check that |
| 602 | * it is still running. As soon as you release the locks, the connection might |
| 603 | * get dropped, though. |
| 604 | * |
| 605 | * On the other hand, hci_conn_hold() and hci_conn_drop() are used to control |
| 606 | * how long the underlying connection is held. So every channel that runs on the |
| 607 | * hci_conn object calls this to prevent the connection from disappearing. As |
| 608 | * long as you hold a device, you must also guarantee that you have a valid |
| 609 | * reference to the device via hci_conn_get() (or the initial reference from |
| 610 | * hci_conn_add()). |
| 611 | * The hold()/drop() ref-count is known to drop below 0 sometimes, which doesn't |
| 612 | * break because nobody cares for that. But this means, we cannot use |
| 613 | * _get()/_drop() in it, but require the caller to have a valid ref (FIXME). |
