As the number of LLM-generated patches in my inbox increases, I am starting to experience the sort of maintainer stress that has long been predicted. But there's another aspect of this that has recently crossed my mind.

Just over a week ago, a new personality showed up with a whole pile of machine-generated patches claiming to fill in our memory-management documentation. A few reviewers had some sharp questions, the response to which has been ... silence. This person doesn't seem to have cared enough about that work to make an effort to get past the initial resistance.

Once upon a time, somebody who had produced many pages of MM documentation would be invested enough in that work to make at least a minimal attempt to defend it.

Kernel developers often worry that a patch submitter will not stick around to maintain the code they are trying to push upstream. Part of the gauntlet of getting kernel patches accepted can be seen as a sort of "are you serious?" test.

When somebody submits a big pile of machine-generated code, though, will they be *able* to maintain it? And will they be sufficiently invested in this code, which they didn't write and probably don't understand, to stick around and fix the inevitable problems that will arise? I rather fear not, and that does not bode well for the long-term maintainability of our software.

@corbet I fear the precedent accepting this kind of thing will establish.

Not only in terms of asymmetric levels of AI slop vs. maintainer resource, but also concerns around social engineering from bad actors (not this doc patch but other recent, clearly AI, series).

Sadly mm is being run in a very chaotic fashion where, without pushback from sub-maintainers, we would just take this kind of thing.

It's very tiring to have to constantly be on alert for that, and I hope at some point the culture will change and we can move away from default-take-everything mode.

Another issue here is that it's often hard to really call out AI even if it really seems like it - if somebody denies it, you don't want it to turn into a witch trial.

As always, many social issues at play :)
