* mte_set_parent() - Set the parent node and encode the slot.
+ * @node: The encoded maple node.
+ * @parent: The encoded maple node that is the parent of @node.
+ * @slot: The slot that @node resides in @parent.
*
* Type is encoded in the node->parent
* bit 0: 1 = root, 0 otherwise
- * bit 1: 0 = range 16, 1 otherwise
+ * bit 1: Reserved.
* bit 2: 0 = range 32, 1 = [a]range 64 | lowest bit of range_16's slot.
*
* Slot number is encoded in the node->parent
- * range_16, slot number is encoded in bits 2-6
* range_32, slot number is encoded in bits 3-6
* [a]range_64, slot number is encoded in bits 3-6
