| Subject: radix tree: remove unused variable |
| Date: Fri, 11 Aug 2023 15:10:13 +0200 |
| |
| Recent versions of clang warn about an unused variable, though older |
| versions saw the 'slot++' as a use and did not warn: |
| |
| radix-tree.c:1136:50: error: parameter 'slot' set but not used [-Werror,-Wunused-but-set-parameter] |
| |
| It's clearly not needed any more, so just remove it. |
