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.
