ftrace: Hide cached module code for !CONFIG_MODULES (69449bbd) · Commits · 戴 / test

When modules are disabled, we get a harmless build warning: kernel/trace/ftrace.c:4051:13: error: 'process_cached_mods' defined but not used [-Werror=unused-function] This adds the same #ifdef around the new code that exists around its caller.
