It's a good idea.
Below is another proposition (untested) that panics if
rte_log_register() fails, and that defines a static variable with a
predefined name.
#define RTE_LOG_TYPE_REGISTER(name, level) \
static int name##_log_type; \
__attribute__((constructor, used)) \
static void rte_log_register_##name(void) \
{ \
name##_log_type = rte_log_register(#name); \
RTE_VERIFY(name##_log_type >= 0); \
rte_log_set_level(name##_log_type, level); \
}
