perf tests: Do not use sizeof on pointer type (2016-04-28 15:37:52 -0300)
---------------------------------------------------------------- perf/core improvements and fixes:
User visible:
- Allow generate timestamped suffixed multiple perf.data files upon receiving SIGUSR2 in 'perf record', to slice a long running monitoring session, allowing to dump uninteresting sessions (Wang Nan)
- Handle ENOMEM for perf_event_max_stack + PERF_SAMPLE_CALLCHAIN in perf_evsel__open_strerror(), showing a more informative message when the request call stack depth can't be allocated by the kernel (Arnaldo Carvalho de Melo)
Infrastructure:
- Use strbuf for making strings in 'perf probe' (Masami Hiramatsu)
- Do not use sizeof on pointer type, not a problem since its a pointer to pointer, fix none the less. Found by Coccinelle (Vaishali Thakkar)
Cleanups:
- Fix for Coverity found issues in the bpf feature build test (Florian Fainelli)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
---------------------------------------------------------------- Arnaldo Carvalho de Melo (3): perf evsel: Handle ENOMEM for perf_event_max_stack + PERF_SAMPLE_CALLCHAIN perf evsel: Remove two extraneous ending newlines in open_strerror() perf trace: Move msg_flags beautifier to tools/perf/trace/beauty/
Florian Fainelli (2): bpf tools: Remove expression with no effect bpf tools: Fix syscall argument
Masami Hiramatsu (1): perf probe: Use strbuf for making strings
Vaishali Thakkar (1): perf tests: Do not use sizeof on pointer type
Wang Nan (6): perf tools: Introduce trigger class perf tools: Derive trigger class from auxtrace_snapshot perf record: Split output into multiple files via '--switch-output' perf record: Force enable --timestamp-filename when --switch-output is provided perf record: Disable buildid cache options by default in switch output mode perf record: Generate tracking events for process forked by perf
