The intersection of modules, GKI, and rocket science
One does not normally expect a lot of controversy around a patch series that makes changes to platform-specific configurations and drivers. The furor over some work on the Samsung Exynos platform may thus be surprising.lwn.net

eBPF Instruction Sets
Not everyone who develops BPF programs knows that several versions of the instruction set exist. This isn’t really surprising given documentation on the subject is scarce.pchaigno.github.io
fs-verity support in btrfs: Detect tampering in critical read-only files

I think we're where we want to be in terms of peak, next round of work will be (again) diminishing the impact of things like blk-cgroup, and other block/kernel options that have an adverse performance impact.[/bookmark]
"How a simple Linux kernel memory corruption bug can lead to complete system compromise: An analysis of current and potential kernel security mitigations"
I'll post a copy to the kernel-hardening list later in case folks want to discuss it.

Using lei, b4, and mutt to do kernel development
tl;dr Use b4 to apply random patches locally for patch review. Use lei to pull down emails and pathces you care about for all linux kernel mailinglists locally. Use mutt to read that email and respond.josefbacik.github.io
"[…] I'd love to say that it's all looking average, but rc6 is actually bigger han rc5 was, and larger than normal for this time in the release cycle. […] slightly worrisome[…]"

TL;DR: Memory-Model Recommendations for Rusting the Linux Kernel
These recommendations assume that the initial Linux-kernel targets for Rust developers are device drivers that do not have unusual performance and scalability requirements, meaning that wrappering of small C-language functions is tolerable.paulmck.livejournal.com
