AI Is Now Being Used To Help Determine Patches For Backporting In The Linux Kernel

([Linux Kernel] 5 Hours Ago Should This Patch Be Backported?)


Generative AI "GenAI" is now being used in part to help determine the Linux kernel patches that should be back-ported to prior current stable Linux kernel releases such as the all-important Linux Long Term Support (LTS) branches.

Linux LTS co-maintainer Sasha Levin was the one helping push along [1]the recent Linux kernel documentation around AI coding assistant use . It now appears Sasha Levin is using AI/LLMs to help in figuring out the patches that should be back-ported to existing Linux kernel releases.

Typically kernel developers will "CC: stable" for patches that are explicitly marked for back-porting from the Linux upstream Git to prior releases. For patches not explicitly being marked, AI is now helping out given the demanding challenges of the upstream Linux LTS maintenance.

Sasha Levin is employed by NVIDIA as a "Linux kernel hacker" and with patches for back-porting sent out by this Linux LTS co-maintainer there's beginning to be LLM-generated messages. Such as [2]this patch this week adding:

LLM Generated explanations, may be completely bogus:

Now I have a better understanding. Let me analyze the commit to determine if it should be backported:

**Backport Status: YES**

## Extensive Explanation:

This commit should be backported to stable kernel trees for the following reasons:

...

The large language model generated response then goes on to note that the particular patch fixes a user-facing problem, it's a regression fix, limited scope and low-risk of causing issues, and a hardware-specific fix, among other details in favor of back-porting the patch to Linux kernel stable releases.

There are similar AI/LLM-generated messages with [3]other patches posted this week for back-porting too.

It will be interesting to see moving ahead what more AI usage is found for assisting the upstream Linux kernel development.

After the Children of Israel had wandered for thirty-nine years
in the wilderness, Ferdinand Feghoot arrived to make sure that they would
finally find and enter the Promised Land. With him, he brought his
favorite robot, faithful old Yewtoo Artoo, to carry his gear and do
assorted camp chores.
The Israelites soon got over their initial fear of the robot and,
as the months passed, became very fond of him. Patriarchs took to
discussing abtruse theological problems with him, and each evening the
children all gathered to hear the many stories with which he was programmed.
Therefore it came as a great shock to them when, just as their journey was
ending, he abruptly wore out. Even Feghoot couldn't console them.
"It may be true, Ferdinand Feghoot," said Moses, "that our friend
Yewtoo Artoo was soulless, but we cannot believe it. He must be properly
interred. We cannot embalm him as do the Egyptians. Nor have we wood for
a coffin. But I do have a most splendid skin from one of Pharoah's own
cattle. We shall bury him in it."
Feghoot agreed. "Yes, let this be his last rusting place."
"Rusting?" Moses cried. "Not in this dreadful dry desert!"
"Ah!" sighed Ferdinand Feghoot, shedding a tear, "I fear you do not
realize the full significance of Pharoah's oxhide!"
