Hello, All.

Will we be able to add some kernel performance tests? Especially, filesystem and io schedulers ones.

Last year I had an issue when my system having been upgraded to 12.3 was becoming unusable due to deadlock in reiserfs quota routines within 5 minutes after boot. Majority of processes just were in d state.

Would be great to have an automatic tool to avoid similar issues in futute.

You can do a lot of things with automated tests, but I think it's unreasonable to expect someone (else) to write a test case for reiserfs quota.

But enabling interested people to (easily) write test cases is a mid term goal. Which of them we want to run and when is another discussion. Test suites can be quite unfair to the one looking at them - you have to often dig if the test is broken or the software you're testing. This is especially true for performance tests. So this needs to be done with extra care.

Also performance test can be tricky in a KVM environment where there are many other instances running at the same time. But I am sure that the use case expressed by Matwey (detecting regressions in the performance) is something that can be done until some extend.

Ok, I see. If it were relatively easy I would try to make a couple of tests. The question is not about reiser only, but about each filesystem or storage subsystem. Unfortunately, things like this happen sometimes: http://lists.opensuse.org/opensuse-factory/2014-01/msg00294.html I don't like when release eats my data or crash my kernel. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
