Linux 7.3 Network Integration Flooded by 648 AI Patches, Maintainers 'Completely Overwhelmed'

Network Subsystem Integration Completed

According to a report by Phoronix’s Michael Larabel, feature updates belonging to the Linux 7.3 kernel’s network subsystem were merged on August 20, 2026, during the merge window. While this round includes numerous improvements for both wired and wireless networking, the volume of bug fixes is also substantial. Many of these are low-importance fixes generated by AI/LLM agents. The network subsystem maintainer expressed feeling “completely overwhelmed” by the influx of code from AI large language models.

Flood of AI Patches and Maintainer Burden

Maintainer Jakub Kicinski disclosed specific figures in the Linux 7.3 network pull request. 632 net patches and 648 net-next patches were integrated. However, this number doesn’t tell the whole story. It appears that one-third to one-half of the net-next patches are AI-driven, low-priority fixes, cleanups, and clarifications. The development team has been under a sustained patch bombardment for months and has resorted to deleting old network code and drivers. This measure aims to reduce the noise from AI patches by removing drivers that are likely no longer used in modern kernel environments. Despite this, the activity of LLM agents shows no signs of slowing down.

Review Response Using LLM Budget Provided by Meta

Kicinski revealed that maintainers have secured a substantial LLM budget and access from Meta. By utilizing multiple frontier models for patch review, some hallucinations can be eliminated. However, there are limits to what LLMs can handle in reviews. Kicinski pointed out:

“The sad truth is that our APIs (especially for rare events like PCIe errors, timeouts) are always racy, and we now can’t let LLMs ignore that.”

Planned Strategic Shift to Utilize LLMs

Looking ahead, Kicinski hinted at plans to shift focus from merely fine-tuning review methods to leveraging LLMs for everyday tasks. Candidate tasks include managing patchwork, automating common process complaints, editing commit messages, and applying patches that have received a “reviewed-by” tag from a trusted individual. A rather ironic picture emerges: using AI to combat the flood of AI-generated patches themselves.

Major Technical Changes Related to Networking

In this round’s technical changes, BIG TCP support over UDP tunnels was added for the VXLAN and Geneve drivers. MPTCP (Multipath TCP) processing was improved under extreme memory pressure. Wired network drivers include initial CXL support for AMD/Solarflare NICs, an initial skeleton for the Intel iXD driver, and firmware flash support for AMD Pensando NICs. Behind the chaos of AI patches, the network infrastructure itself is steadily evolving.

Editorial Opinion

Short-term Impact: The increased burden on developers from AI-generated patches is not a problem confined to the Linux kernel community. Within the next 3-6 months, similar situations may become apparent in other large-scale OSS projects. Meta’s provision of an LLM budget could become a pioneering model for how major tech companies channel AI utilization back into OSS activities. Attention will be on the moves of other companies as well.

Long-term Perspective: A structural shift towards integrating AI as a “development collaborator” in OSS is inevitable. How the Linux kernel community addresses this issue will set a precedent affecting other projects. The policy of having LLMs apply patches reviewed by a trusted individual raises the fundamental question of where to draw the line between human judgment and AI automation.

Question from the Editorial Board: If automatic application of patches with the “reviewed-by” tag is introduced, how will the value and credibility of the tag change? Is there a risk that the trust backed by human review becomes diluted within an automated process?
