The whole series is out as an RFC, I am not sure I will manage to convince upstream to merge this.. but I am quite proud of being able to accomplish this. Let's hope it does not cause too much controversy. https://lore.kernel.org/all/20260712013941.4570-1-fmancera@suse.de/T/#m34b192be30888c6bf6f7dbfd42c22381716b3f50 #ipv6 #linux

@karhima@graz.social @nik@toot.teckids.org The account is needed to participate in any platform, forum or site from Fedora. I mean, sure it isn't exactly the same but similar. It is "banning" people under 16 to be able to participate. Not defending it in any way tho, I was trying to point out that it is a trend and it is BAD.

@karhima@graz.social @nik@toot.teckids.org It is not on any docs I could find. If you try to create a Fedora Account it shows this (at least in Spain).

@nik@toot.teckids.org I wonder where this come from, I recently noticed in Fedora too. Not sure if it is new there, but in essence you need to confirm that you are at least 16 years old.

@jzb@hachyderm.io Yes you are right. Unfortunately that is the society where we live in. I myself have found people clearly using AI for everything that denied its usage. The major problem I faced is that I cannot prove it. They always argue, that they did it on their own or it is their writing style. Everything makes me quite sad recently..

@ljs@mastodonapp.uk Well, between these patches there are AI slopped KASAN traces and also non-real bugs. What I find annoying is that when you push back, you get a huge wall of text that takes a lot of time to understand and ush back again

This is a joke the AI guy is now sending reviews to patches related to a Magnetometer - the guy went from wireless driver to HSR/PRP to Magnetometer. In a week or so.

Replying to @gregkh@social.kernel.org
@gregkh a pattern I have seen recently is new people on kernel reporting bugs on random subsystems. I am pretty sure they just feed the code to a LLM and send whatever it found. E.g yesterday I got a review on a patch I sent a year ago on protocol that is pretty uncommon. After talking to the reviewer, it is clearly an AI. It is by the way, the same person that sent a 22 patches series for rtl8723bs that you needed to review :/

The kernel patch series removing IPV6=m is out! I am quite happy about it and I hope I did not mess up :)

A lot of people were CC'ed, sorry about the noise ^^
