Linux Kernel Daily: Late-Cycle Fixes Across Rust, Perf Tools, and LoongArch
Four merge commits landed as release-candidate fixes for the seven-point-two cycle, spanning Rust toolchain compatibility, perf tools header syncing, LoongArch stability, and a firewire networking bug — all late-stage hardening rather than new feature work.

Good evening. It's July 26th, 2026, and this is Linux Kernel Daily.
Tonight's activity is a clear signal: this is release-candidate cleanup season. Four merge commits, zero open pull requests — all fixes, no features, all aimed at stabilizing the seven-point-two release before it ships.
The biggest theme is forward compatibility with upcoming toolchains. Commit 3-D-A-B-1-3-9 pulls in Rust fixes from Miguel Ojeda, and most of the work is defensive: cleaning up lint errors and adding a "noreturn" annotation specifically to prepare for Rust 1.99, which isn't expected until October. There's also a real…
Second theme: housekeeping for tooling accuracy. Commit E-F-9-C-E-8-0 syncs perf's copies of kernel headers — KVM, filesystem, CPU features, DRM, socket definitions, and more. This is routine but important: perf tools drift from the kernel headers they mirror, and unsynced copies can cause subtle build or…
Third theme: architecture-specific correctness on LoongArch. Commit 3-F-B-1-1-7-0 bundles ten fixes — a kexec address space mismatch, a single-step debugging oops, a BPF JIT memory leak, and a fix for signed division results in 32-bit ALU operations. Notably, jump label initialization…
