[PATCH 2/2] perf trace: Guard __probe_ip suppression with evsel__is_probe()

From: Arnaldo Carvalho de Melo

Date: Tue Jun 16 2026 - 11:54:54 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

trace__fprintf_tp_fields() compares every field name against
"__probe_ip" for all tracepoint events, but this field is only
implicitly added by the Ftrace subsystem to bare dynamic probes.

Add an evsel__is_probe() check before the strcmp so the string
comparison is skipped entirely for non-probe events.
