From 721a1f53df6aad3ea941f5fe95519d0d8e02bd65 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 19 Nov 2015 12:01:48 -0300 Subject: perf tests: Pass the subtest index to each test routine 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.
