If that can work for us, then IIUC we can avoid either "since:" or any relevant flag, neither do we need to unmask tests after each releases. All old tests should always "just work" with a new qemu binary. One drawback I can think of is, new tests (even if applicable to old qemu binaries) will only start to take effect on cross-binary test until the next release, but that's not so bad I assume. Since the QTEST_QEMU_BINARY_SRC|DST function is already merged in 8.2, I think we can already start kicking them and enable them for 9.0 if it works. -- Peter Xu
