In a plenary session at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, the state of patch review using large language models (LLMs) was discussed. It is a topic that has been swirling around in the kernel community for much of the year. The plenary, which was led by Roman Gushchin, Chris Mason, Josef Bacik, and Sasha Levin, resulted in a quite bit of discussion, so much that a second filesystem-track-only (though others surely sat in) slot was used to continue it later in the day.

The Software Freedom Conservancy (SFC) published a news item on May 18 about its response to violations of the AGPLv3 by Bambu Lab in its 3D printers. The company has not provided the source code to its modifications to a 3D "slicer" program that was released under the AGPLv3 and it has also threatened Paweł Jarczak who created a fork of a different slicer (Orca Slicer) released under AGPLv3 in order to interoperate with his Bambu printer. Based on that, the SFC has created the baltobu project aimed at reverse-engineering and reimplementing the Bambu code while also hosting the Orca Slicer fork.

Bambu has behaved badly for years and made multiple, provably false public statements regarding the AGPLv3 and its requirements. The recent aggressive behavior toward Paweł Jarczak was a last straw for us: we have decided to launch a multi-pronged effort that will assist consumers and users in the short-term, and also work toward a long-term strategy to improve the software right to repair for all 3D printer consumers.

Joshua Hahn began his session in the memory-management track of the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit by saying that the memory controller for control groups is intended to provide resource allocation, accounting, and protection from interference by other tasks. But it was not really designed for tiered-memory systems; he is looking for a way to improve that situation.

Linus Torvalds does not enjoy giving talks, but he does consent to the occasional on-stage conversation with Dirk Hohndel at Linux Foundation events. The pair held the 30th of their fire-less fireside chats during a keynote session on May 20, at the 2026 Open Source Summit North America. Topics included 3D printing, guitar pedals, the recent 7.1-rc4 release of the kernel, and Torvalds's complicated relationship with AI tooling.
