Not sure what you want..

As I found it from code inspection I don't know if there's a test covering this.

But as far as I can see, 2 of them are on the error path so maybe not easy
to add a test, other one is called from perf list code, and the last one is on
the normal code path so any test should cover it.

Thanks
