  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
