#define __for_each_mod_mem_types(type, _from, _to)	\
	for (enum mod_mem_type type = _from; type <= _to; type++;)

also to be used in the previously suggested within_module_mem_types()
function.

also note the C99 variable in for-loop decl thing

#define for_code_mod_mem_type(type)			\
	__for_each_mod_mem_types(type, MOD_TEXT, MOD_RO_AFTER_INIT)

#define for_code_mod_mem_type(type)			\
	__for_each_mod_mem_types(type, MOD_INIT_TEXT, MOD_INIT_RODATA)
