Thank you for pointing it out, I just reused the description which I sent last year. It needs to be updated. ----- Currently, kprobe event checks whether the target symbol name is unique, so that it does not put a probe on unexpected place. But this skips the check if the target is on a module. This fixes the issue by checking the symbol is unique in the target module if the target is on a module. ----- Thanks! > > -- Steve -- Masami Hiramatsu (Google) <mhira...@kernel.org>
