      由 Arnaldo Carvalho de Melo 提交于 
      The callers of this function (perf_event__process_tracing_data) already
handles a negative value return as error, so just use pr_err() to log
the problem and return -1 instead of panic'ing.

      tools lib traceevent: Handle dynamic array's element size properly · e23c1a55
      由 Jiri Olsa 提交于 
      Fixing the dynamic array format field parsing.

Currently the event_read_fields function could segfault while parsing
dynamic array other than string type. The reason is the event->pevent
does not need to be set and gets dereferenced unconditionaly.

Also adding proper initialization of field->elementsize based on the
parsed dynamic type.

      perf test: Allow skipping tests · 2ae82878
      由 Arnaldo Carvalho de Melo 提交于 
      Sometimes a test is problematic for some reason and one wants to skip it,
for instance:

[root@sandy ~]# perf test
   1: vmlinux symtab matches kallsyms                        : Ok
   2: detect open syscall event                              : Ok
   3: detect open syscall event on all cpus                  : Ok
   4: read samples using the mmap interface                  : Ok
   5: parse events tests                                     :  Warning: bad op token {
    Warning: bad op token {
    Warning: bad op token {
    Warning: bad op token {
    Warning: bad op token {
    Warning: function is_writable_pte not defined
  Segmentation fault (core dumped)

So now we can use -s/--skip while the problematic tests are being fixed,
allowing us to test all the other entries:

  [root@sandy ~]# perf test -s 5
   1: vmlinux symtab matches kallsyms                        : Ok
   2: detect open syscall event                              : Ok
   3: detect open syscall event on all cpus                  : Ok
   4: read samples using the mmap interface                  : Ok
   5: parse events tests                                     : Skip (user override)
   6: x86 rdpmc test                                         : Ok
   7: Validate PERF_RECORD_* events & perf_sample fields     : Ok
   8: Test perf pmu format parsing                           : Ok
   9: Test dso data interface                                : Ok
  10: roundtrip evsel->name check                            : Ok
  11: Check parsing of sched tracepoints fields              : Ok
  12: Generate and check syscalls:sys_enter_open event fields: Ok
  13: struct perf_event_attr setup                           : Ok
