937 | * working or anything else. They just guarantee that the object is available |
938 | * and can be dereferenced. So you can use its locks, local variables and any |
939 | * other constant data. |
940 | * Before accessing runtime data, you _must_ lock the object and then check that |
941 | * it is still running. As soon as you release the locks, the connection might |
942 | * get dropped, though. |
943 | * |
944 | * On the other hand, hci_conn_hold() and hci_conn_drop() are used to control |
945 | * how long the underlying connection is held. So every channel that runs on the |
946 | * hci_conn object calls this to prevent the connection from disappearing. As |
947 | * long as you hold a device, you must also guarantee that you have a valid |
948 | * reference to the device via hci_conn_get() (or the initial reference from |
949 | * hci_conn_add()). |
950 | * The hold()/drop() ref-count is known to drop below 0 sometimes, which doesn't |
951 | * break because nobody cares for that. But this means, we cannot use |
952 | * _get()/_drop() in it, but require the caller to have a valid ref (FIXME). |
