+ * tbl_next - find next node in hash table
+ * @table: table to iterate
+ * @bucketp: On entry, hash value of bucket to start from. On exit, updated
+ * to bucket to start from on next call.
+ * @objp: On entry, index to start from within first bucket. On exit, updated
+ * to index to start from on next call.
+ *
+ * Returns the next node in @table in hash order, or %NULL when no nodes remain
+ * in the hash table.
+ *
+ * On entry, uses the values that @bucketp and @objp reference to determine
+ * where to begin iteration. Use 0 for both values to begin a new iteration.
+ * On exit, stores the values to pass on the next iteration into @bucketp and
+ * @objp's referents.
