Linux kernel 6.6 introduced CONFIG_LIST_HARDENED, of which CONFIG_DEBUG_LIST is a superset [1]. Since CONFIG_DEBUG_LIST selects CONFIG_LIST_HARDENED, configs that already selected CONFIG_DEBUG_LIST were not prompted for CONFIG_LIST_HARDENED. Since CONFIG_DEBUG_LIST has never been designed with performance in mind, non-debug kernels should prefer CONFIG_LIST_HARDENED. The main benefit is improved performance; the only downside is slightly worse error reporting (the WARNING is turned into an access fault in some cases). Hardening-wise there is no functional difference.
