|  | ABI testing symbols | 
|  | =================== | 
|  |  | 
|  | Documents interfaces that are felt to be stable, | 
|  | as the main development of this interface has been completed. | 
|  |  | 
|  | The interface can be changed to add new features, but the | 
|  | current interface will not break by doing this, unless grave | 
|  | errors or security problems are found in them. | 
|  |  | 
|  | Userspace programs can start to rely on these interfaces, but they must | 
|  | be aware of changes that can occur before these interfaces move to | 
|  | be marked stable. | 
|  |  | 
|  | Programs that use these interfaces are strongly encouraged to add their | 
|  | name to the description of these interfaces, so that the kernel | 
|  | developers can easily notify them if any changes occur. |
