kees@hachyderm.ioI've been playing with the LLM code assistants, trying to stress them out with the Linux kernel code. So far, I've had success with them writing reasonable unit tests:

https://lore.kernel.org/lkml/20250724030233.work.486-kees@kernel.org/
These both saved me some time since it emitted quite a lot of good boundary testing code, but I had to massage them both a bit until I was happy with the coverage. But it was a net win on time spent.
And then I walked it through fixing a buffer overflow. This one didn't save me any time because I had to tell it how to look at the problem. Since it was a shorter/simpler session, I included my exact prompts just for anyone interested in what I did:

kees@hachyderm.ioThis graph is the one I'm most excited about: the lifetime of security flaws in Linux is finally starting to get shorter (and the number of fixed flaws continues to rise).

Personally I use it to rephrase/proofread text or quickly look something up (as a first resort before grepping through git history or mailing list archive). I heard AUTOSEL uses LLMs to determine whether a patch should be backported to -stable or not.
But at this point, I really hope no one sends any code written or guided by AI to the mailing list. It might be fine to get shallow reviews of human-written code from LLMs, but I doubt they're capable of writing sane kernel code or offering deep reviews.
