You've misunderstood. Google have decided to subject the entire kernel (including obsolete unmaintained filesystems) to stress tests that it's never had before. IOW these bugs have been there since the code was merged. There's nothing to back out. There's no API change to blame. It's always been buggy and it's never mattered before.
I'm not blaming the unstable API for the bugs, I'm blaming it for the workload. A stable API (like a userspace API) decreases the likelihood that overloaded maintainers have to orphan a filesystem implementation.
