 /*
+ * Clang 22 added preprocessor macros to match GCC, in hopes of eventually
+ * dropping __has_feature support for sanitizers:
+ * https://github.com/llvm/llvm-project/commit/568c23bbd3303518c5056d7f03444dae4fdc8a9c
+ * Create these macros for older versions of clang so that it is easy to clean
+ * up once the minimum supported version of LLVM for building the kernel always
+ * creates these macros.
+ *
  * Note: Checking __has_feature(*_sanitizer) is only true if the feature is
  * enabled. Therefore it is not required to additionally check defined(CONFIG_*)
  * to avoid adding redundant attributes in other configurations.
