Congrats to the team for tracking this down, it was a great write-up!

Twitter has some great networking/kernel engineers. When I was working at Twitter a few years back we isolated and fixed another insidious kernel bug; a large group was critical to making it happen (including Cong, who worked on this bug): https://tech.vijayp.ca/linux-kernel-bug-delivers-corrupt-tcp...

I'm always shocked at how the kernel seems to mostly work, with such meagre test coverage. I guess testing in production does kind of work at scale?
