Oops, I might miss something, forgot it. actually, current perf probe doesn't decode kallsyms/elf, it just depends on kprobe-tracer. And kprobe-tracer will return -EINVAL not only if the symbol was not found, but also other reasons.
So, if we want to show below message, we need to decode elf or kallsyms.
