-enum maple_type mas_parent_type(struct ma_state *mas, struct maple_enode *enode)
+enum maple_type ma_parent_type(struct maple_tree *mt, struct maple_node *node)

I was trying to keep ma_* prefix to mean the first argument is
maple_node and mt_* to mean maple_tree.  I wasn't entirely successful
with this and I do see why you want to use ma_, but maybe reverse the
arguments here?

I think your first idea is better.  Usually we prefer to order the
arguments by "containing thing" to "contained thing".  So always use
(struct address_space *, struct folio *), for example.  Or (struct
mm_struct *, struct vm_area_struct *).

There are disagreements here, so how to decide? But I don't know if the
new version still has this helper.

Please keep the maple tree as the first argument and use:
mt_parent_type as the name.. if you still need it.
