The workqueue changes merged today for the Linux 7.1 kernel are significant for today's modern high-end processors where there can be many CPU cores per last level cache (LLC / L3 cache). The new WQ_AFFN_CACHE_SHARD affinity scope can reduce some contention on such systems and help achieve greater performance.

Last month I ran benchmarks showing the very positive performance impact FRED has on Intel's new Panther Lake processors while wondering why Flexible Return and Event Deliver wasn't enabled by default yet on Linux. Hours after that story was published, an Intel engineer posted the patch to enable FRED by default with the rationale they were waiting for hardware to be publicly released in order to evaluate the performance benefit. Days after that the FRED-by-default patch hit tip/tip.git and now as of yesterday that patch is merged for Linux 7.1.

Code now merged for the Linux 7.1 kernel may provide some negative performance implications for those still running modern Linux kernels on 32-bit hardware. A fundamental change can present cache line alignment and slab sizing implications for 32-bit Linux OS users but will provide for cleaner code with modern 64-bit computing.
