Linus has released 6.19-rc1, perhaps a bit earlier than expected.
So it's Sunday afternoon in the part of the world where I am now, so if somebody was looking at trying to limbo under the merge window timing with one last pull request and is taken by surprise by the slightly unusual timing of the rc1 release, that failed.Teaching moment, or random capricious acts? You be the judge.

Ariadne Conill is exploring a capability-based approach to privilege escalation on Linux systems.
Inspired by the object-capability model, I've been working on a project named capsudo. Instead of treating privilege escalation as a temporary change of identity, capsudo reframes it as a mediated interaction with a service called capsudod that holds specific authority, which may range from full root privileges to a narrowly scoped set of capabilities depending on how it is deployed.

The ability to write kernel code in Rust was explicitly added as an experiment — if things did not go well, Rust would be removed again. At the 2025 Maintainers Summit, a session was held to evaluate the state of that experiment, and to decide whether the time had come to declare the result to be a success. The (arguably unsurprising) conclusion was that the experiment is indeed a success, but there were some interesting points made along the way.

One of the key components in the kernel's development process is the linux-next repository. Every day, a large number of branches, each containing commits intended for the next kernel development cycle, is pulled into linux-next and integrated. If there are conflicts between branches, the linux-next process will reveal them. In theory, many other types of problems can be found as well. Some developers feel that linux-next does not work as well as it could, though. At the 2025 Maintainers Summit, Mark Brown, who helps to keep linux-next going, led a session on how it could be made to work more effectively.
