Merge tag 'probes-v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull probes update from Masami Hiramatsu:
- Update the Kprobes trace event to show the actual function name in
notrace-symbol warning.
Instead of using the user specified symbol name, use "%ps" printk
format to show the actual symbol at the probe address. Since kprobe
event accepts the offset from symbol which is bigger than the symbol
size, the user specified symbol may not be the actual probed symbol.

trace/kprobe: Display the actual notrace function when rejecting a probe
