Linux Kernel 7.2-rc4 Drops: Cache-Aware Scheduling, MongoDB Speedups, and the End of strncpy
The fourth release candidate for Linux Kernel 7.2 hit the wire on July 19, 2026, pushing the codebase past 43 million lines while Linus Torvalds confirms that steady patch flows and AI-assisted bug hunting are officially the new normal. Cache-Aware Scheduling finally arrives to optimize task placement across complex CPU topologies, delivering measurable performance gains for AMD Zen 5 workloads and boosting MongoDB throughput by up to 100 percent. The kernel also cleans house with Btrfs large folios enabled by default, initial HDMI 2.1 FRL support in AMDGPU, and the permanent retirement of the strncpy API after six years of cleanup. You can expect the stable release in August 2026, though the ongoing purging of decades-old drivers and legacy code means the tree is already moving at a relentless pace.
