| Subject: maple_tree: arange64 node is not a leaf node |
| Date: Mon, 26 Aug 2024 01:24:21 +0000 |
| |
| mt_dump_arange64() only applies to an entry whose type is maple_arange_64, |
| in which mte_is_leaf() must return false. |
| |
| Since mte_is_leaf() here is always false, we can remove this condition |
| check. |
