Linux Kernel Subsystems & Performance Audit

From an operating systems and systems programming perspective: - **Upstream Cohesion:** Merging patches upstream prevents fragmented fork debt and guarantees binary compatibility. - **Attack Surface Reduction:** Stripping obsolete legacy subsystems strengthens real-world operational security. - **Resource Determinism:** Enhancements to scheduling and memory management minimize jitter in high-throughput workloads.

Impact on the Open Ecosystem

Ensures kernel infrastructure remains auditable, stable under heavy load, and compliant with modern reproducibility standards.
