I tried to run the build-test after I fetched the branch
acme/tmp.perf-tools-next and found errors; seems the errors are not
related with perf kvm but it's good to check a bit.

The complete building log is in the link:

Later I think it would be a good habit to run build-test on my
patches locally :)

Thanks,
