/// 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.
