In some compilers we get:
tests/sw-clock.c: In function ‘__test__sw_clock_freq’:
tests/sw-clock.c:35: error: unknown field ‘sample_freq’ specified in initializer
So I'm moving the initialization to outside the struct named initialization
block, i.e.:
@@ -32,9 +32,10 @@ static int __test__sw_clock_freq(enum perf_sw_ids clock_id)
.exclude_kernel = 1,
.disabled = 1,
.freq = 1,
- .sample_freq = 10000,
};
+ attr.sample_freq = 10000;
