/// If list_for_each_entry, etc complete a traversal of the list, the iterator |
|
/// variable ends up pointing to an address at an offset from the list head, |
|
/// and not a meaningful structure. Thus this value should not be used after |
|
/// the end of the iterator. |
|
//#False positives arise when there is a goto in the iterator and the |
|
//#reported reference is at the label of this goto. Some flag tests |
|
//#may also cause a report to be a false positive. |
