After this patch, the output may becomes: [ 55.225555] Probe 0 : perf_trace_sched_wakeup_template+0x0/0x20 Link: https://lore.kernel.org/20250307033858.4134-1-shijie@os.amperecomputing.com Signed-off-by: Huang Shijie Signed-off-by: Steven Rostedt (Google) --- diff --git a/kernel/tracepoint.c b/kernel/tracepoint.c index 1848ce7e2976..62719d2941c9 100644 --- a/kernel/tracepoint.c +++ b/kernel/tracepoint.c @@ -127,7 +127,7 @@ static void debug_print_probes(struct tracepoint_func *funcs) return; for (i = 0; funcs[i].func; i++) - printk(KERN_DEBUG "Probe %d : %p\n", i, funcs[i].func); + printk(KERN_DEBUG "Probe %d : %pSb\n", i, funcs[i].func); } static struct tracepoint_func *
