Yes please.
arch/x86/kernel/ftrace.c:
#ifdef CONFIG_MODULES #include <linux/moduleloader.h> /* Module allocation simplifies allocating memory for code */ static inline void *alloc_tramp(unsigned long size) { return module_alloc(size); } static inline void tramp_free(void *tramp) { module_memfree(tramp); } #else /* Trampolines can only be created if modules are supported */ static inline void *alloc_tramp(unsigned long size) { return NULL; } static inline void tramp_free(void *tramp) { } #endif
