| 34 | * @list: used to maintain a list of currently available transports | |

| 37 | * @def: set if this transport should be considered the default | |
| 38 | * @create: member function to create a new connection on this transport | |
| aca00763 | 39 | * @close: member function to discard a connection on this transport |

| 45 | * This is the basic API for a transport module which is registered by the | |
| 46 | * transport module with the 9P core network module and used by the client | |
| 47 | * to instantiate a new connection on a transport. | |
| 48 | * | |
| aca00763 | 49 | * The transport module list is protected by v9fs_trans_lock. |
