After patched, rela information for some sections could
disappear. For example, a function like the following:
"
notrace noinline static int version_proc_show(struct seq_file *m,
void *v)
{
return 0;
}
"
Apart from common rela entries, trace and return thunk mechanism
will generate rela information. Use `notrace` to remove the
effect of trace. Make CONFIG_RETHUNK=n can remove the effect of
return thunk.
