Some tests have sub-tests we want to run, so allow passing this.
Wang tried to avoid having to touch all tests, but then, having the
test.func in an anonymous union makes the build fail on older compilers,
like the one in RHEL6, where:
test a = {
.func = foo,
};
fails.
To fix it leave the func pointer in the main structure and pass the subtest
index to all tests, end result function is the same, but we have just one
function pointer, not two, with and without the subtest index as an argument.

* test__parse_no_sample_id_all - test parsing with no sample_id_all bit set.
|
|
*
|
|
* This function tests parsing data produced on kernel's that do not support the
|
|
* sample_id_all bit. Without the sample_id_all bit, non-sample events (such as
|
|
* mmap events) do not have an id sample appended, and consequently logic
|
|
* designed to determine the id will not work. That case happens when there is
|
|
* more than one selected event, so this test processes three events: 2
|
|
* attributes representing the selected events and one mmap event.
|
|
*
|
|
* Return: %0 on success, %-1 if the test fails.
