I don't believe there's ever been any guarantee that "perf test" from version N of the kernel will always work on a version N+M of the kernel. Perhaps I am wrong, though. If that is a guarantee that the perf developers are willing to stand behind, or have already made, I would love to be corrected and would be delighted to hear that in fact there is a stable, backwards compatible perf ABI.
