- * '--' no nodes falling in this range
- * b4. >|_ _ ! (insert start before existing start)
- *
- * Case a3. resolves to b3.:
- * - if the inserted start element is the leftmost, because the '0'
- * element in the tree serves as end element
- * - otherwise, if an existing end is found immediately to the left. If
- * there are existing nodes in between, we need to further descend the
- * tree before we can conclude the new start isn't causing an overlap
- *
- * or to b4., which, preceded by a3., means we already traversed one or
- * more existing intervals entirely, from the right.
- *
- * For a new, rightmost pair of elements, we'll hit cases b3. and b2.,
- * in that order.
- *
- * The flag is also cleared in two special cases:
- *
- * b5. |__ _ _!|<_ _ _ (insert start right before existing end)
- * b6. |__ _ >|!__ _ _ (insert end right after existing start)
- *
- * which always happen as last step and imply that no further
- * overlapping is possible.
- *
- * Another special case comes from the fact that start elements matching
- * an already existing start element are allowed: insertion is not
- * performed but we return -EEXIST in that case, and the error will be
- * cleared by the caller if NLM_F_EXCL is not present in the request.
- * This way, request for insertion of an exact overlap isn't reported as
- * error to userspace if not desired.
- *
- * However, if the existing start matches a pre-existing start, but the
- * end element doesn't match the corresponding pre-existing end element,
- * we need to report a partial overlap. This is a local condition that
- * can be noticed without need for a tracking flag, by checking for a
- * local duplicated end for a corresponding start, from left and right,
- * separately.
