That's why perf probe uses the offset from '_text'. Normal KASLR will just
moves all symbols. (Finer one will move all symbols randomely)
This should not need to access /proc/kallsyms but vmlinux or SystemMap.
We could just pass in: "_text+offset" too.
So, the idea would be to change the existing create_local_trace_kprobe() and
above functions to indicate the user's offset is to be used against _text and
not address?
