| H A D | map.h | a93e0b23 Tue Apr 16 11:01:22 CDT 2019 Song Liu <songliubraving@fb.com> perf tools: Check maps for bpf programs
As reported by Jiri Olsa in:
"[BUG] perf: intel_pt won't display kernel function"
https://lore.kernel.org/lkml/20190403143738.GB32001@krava
Recent changes to support PERF_RECORD_KSYMBOL and PERF_RECORD_BPF_EVENT
broke --kallsyms option. This is because it broke test __map__is_kmodule.
This patch fixes this by adding check for bpf program, so that these maps
are not mistaken as kernel modules.
