-	 *            '--' 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.
+	/* Descend the tree to search for an existing element greater than the
+	 * key value to insert that is greater than the new element. This is the
