Good morning, it's Monday, October 5th, 2026, and this is Linux Kernel Daily.

Linux 7.3 reached release candidate six, and the signal today is stabilization, not features. Five urgent merges landed back to back, all targeting regressions, races, and hardware correctness late in the cycle.

Our first theme is core concurrency and accounting fixes where the impact is reliability and security. The locking merge fixes a use-after-free when the private futex hash table resizes. For developers, that means heavily threaded applications using private locks could previously hit memory corruption. Related, the…

Second theme is platform and driver correctness, plus user-space builds. The x86 merge, commit 0-6-A-C-0-7-3, stops applying virtual address alignment to huge-page mappings on older A-M-D 15-H systems with custom settings, and drops an unnecessary page-table copy during teardown that triggered a lockdep warning. It…

What's next is testing. With R-C-6 tagged in commit A-9-0-E-E-4-3, maintainers signaled a hard focus on stability. Validate futex-heavy workloads, timer re-arm paths, and S-M-Bus transfers, and hold non-critical changes.

That's it for today. Thanks for listening, and stay…
