![]() Fix a bug in del_perf_probe_events() which returns an error (-ENOENT) even if the probes are successfully deleted. This happens only if the probes are on user-apps and not on kernel, simply because it doesn't clear the previous error. So, without this fix, we get an error even though events are being successfully removed. ------ # ./perf probe -x ./perf del_perf_probe_events Added new event: probe_perf:del_perf_probe_events (on del_perf_probe_events in ... You can now use it in all perf tools, such as: perf record -e probe_perf:del_perf_probe_events -aR sleep 1 # ./perf probe -d \*:\* Removed event: probe_perf:del_perf_probe_events Error: Failed to delete events. ------ This fixes the above error. ------ # ./perf probe -d \*:\* Removed event: probe_perf:del_perf_probe_events ------ Reported-by: Arnaldo Carvalho de Melo <acme@kernel.org> Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Richard Weinberger <richard@nod.at> Link: http://lkml.kernel.org/r/20150527083725.23880.45209.stgit@localhost.localdomain Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
