I think we're in pretty good shape now. There are a few minor comments, only one of which really concerns me. That's the freeing of string streams in the resource-managed string stream tests. I can't quite see how the actual stream is freed after being "fake freed" by the stub. Is there something I'm missing? Otherwise, this seems good enough to go. I fear we're probably past the point where it can make it into 6.6 (pull requests are already being sent out, and I'd really rather have the final version of this soak in linux-next for a while before sending it to Linus. But we'll make it the first thing to go into 6.7, I think.
