| Subject: maple tree: use goto label to simplify code |
| Date: Tue, 24 Jun 2025 13:37:48 +0530 |
| |
| Use the underflow goto label to set the status to ma_underflow and return |
| NULL, as is being done elsewhere. |

| [akpm@linux-foundation.org: add newline, per Liam (and remove one, per akpm)] |
