Hello, and welcome to your Linux Kernel recap for September 21st through September 28th, 2026.
This week: 0 pull request activity items, 30 additional commits this week.
The lead pattern is release hardening focused on correctness, not new features, with the scheduler, virtualization stack, and graphics and platform drivers getting the most attention.
First, scheduling reliability. Tracked in merge 673dab7, cache-aware scheduling saw fixes for last-level cache mis-scheduling, use-after-free in cache grouping statistics, and capacity underestimation across C P U hotplug. Kernel threads are now skipped for cache-aware decisions to make the logic more robust, and P…
Second, virtualization and performance observability. Merge 5ccda18 brings a large set of Intel performance fixes, including guest P E B S virtualization, corrected load-store direction for latency samples, Panther Cove data source and event constraints, and fixes for null dereference, reference leaks, and C P…
Third, device and tracing polish. Merge 6812ce4 centers on graphics stability, with nouveau runtime suspend and resume fixes for newer firmware, plus leak, use-after-free and display fixes across A M D, Intel and…
