So there is already NOKPROBE_SYMBOL() macro to make a blacklist so that we can avoid such recursive faults. We need to identify such place and put the symbols in it as I did on x86.
Only if they are C functions. If they're assembly, NOKPROBE_SYMBOL() doesn't work. The answer there is to move them into a section that is excluded from kprobing. That's what the second patch I've already sent does.
Thanks!
And if you need to put some symbols in assembly which already in another section, you can use _ASM_NOKPROBE(symbol) macro :)
