From 36a9799b2c86fd0f86d54f3eec8ea37ac467be25 Mon Sep 17 00:00:00 2001 From: Zhan Xusheng Date: Wed, 5 Aug 2026 15:05:29 +0800 Subject: [PATCH] maple_tree: remove unused mas_is_root_limits() The last callers of mas_is_root_limits() were removed by commit b8852ef30c67 ("maple_tree: remove maple big node and subtree structs"), together with the maple subtree state (mast_*) code that used it. As a static inline it does not trigger -Wunused-function, so it went unnoticed. Remove it. No functional change.
