I.e. the ongoing discussion SZEDER and I have had about the relative danger of adding this BUG() to this part of the code. I think the best thing to do is just to merge it to "next". Maybe I'm wrong about the BUG() not triggering in a way that someone will spot if we expose this more widely. But we've been having some version of that discussion for the past few months without any any new specifics about *how* it might be raised, just (I think it's fair to say) general paranoia that it might happen somehow/somewhere. Which is fair enough, but I'd think a good way forward with it would be to give it wider exposure during this cycle. If it's triggered somehow it's trivial to amend/revert the tip commit to remove the assertion. If we merge it down I promise I'll (and try to remember to, putting it in my calendar if so...) start some discussion before the next release about whether we'll want to cut the release with that BUG(), which if we don't trigger it by then we'll probably feel confident about keeping. Does that sound like a good way forward? Otherwise the "one alternative way forward[...]" mentioned in [1] is something we could do. 1. https://lore.kernel.org/git/211203.868rx2t0hv.gmgdl@xxxxxxxxxxxxxxxxxxx/
