682 | * hci_conn_get() and hci_conn_put() are used to control the life-time of an | |
683 | * "hci_conn" object. They do not guarantee that the hci_conn object is running, | |
684 | * working or anything else. They just guarantee that the object is available | |
685 | * and can be dereferenced. So you can use its locks, local variables and any | |
686 | * other constant data. | |
687 | * Before accessing runtime data, you _must_ lock the object and then check that | |
688 | * it is still running. As soon as you release the locks, the connection might | |
689 | * get dropped, though. | |
690 | * | |
691 | * On the other hand, hci_conn_hold() and hci_conn_drop() are used to control | |
692 | * how long the underlying connection is held. So every channel that runs on the | |
693 | * hci_conn object calls this to prevent the connection from disappearing. As | |
694 | * long as you hold a device, you must also guarantee that you have a valid | |
695 | * reference to the device via hci_conn_get() (or the initial reference from | |
696 | * hci_conn_add()). | |
697 | * The hold()/drop() ref-count is known to drop below 0 sometimes, which doesn't | |
698 | * break because nobody cares for that. But this means, we cannot use | |
699 | * _get()/_drop() in it, but require the caller to have a valid ref (FIXME). | |
