Subject: maple_tree: fix build failure with W=1 and LLVM=1
Date: Fri, 3 May 2024 17:50:27 +0800
When compiling library code using "make W=1 LLVM=1 lib/", clang generated
the following compilation errors:
lib/maple_tree.c:351:21: error: unused function 'mte_set_full' [-Werror,-Wunused-function]
static inline void *mte_set_full(const struct maple_enode *node)
^
lib/maple_tree.c:356:21: error: unused function 'mte_clear_full' [-Werror,-Wunused-function]
static inline void *mte_clear_full(const struct maple_enode *node)
^
lib/maple_tree.c:361:20: error: unused function 'mte_has_null' [-Werror,-Wunused-function]
static inline bool mte_has_null(const struct maple_enode *node)
^
3 errors generated.
Remove unused static inline functions to resolve compilation errors
with clang.
