The Linux 7.4 merge window is unusually large, approaching 20,000 commits, a spike Linus Torvalds attributes to AI-assisted work entering the main development stream.

7.4 is anticipated to be the year’s LTS release, a factor that can influence patch volume, though the exact timing remains uncertain.

Linus Torvalds issued the first release candidate for Linux kernel 7.4 and highlighted a healthier development model that integrates AI-driven patches.

Security and reliability updates include AMD Zen 6 speculative execution mitigations, improved EDAC memory error detection/correction, and strengthened NTFS3 driver security.

Broad improvements span drivers, filesystems, networking, Rust, BPF, memory management, performance tools, selftests, and Raspberry Pi 10-inch monitor support.

Expanded hardware support covers next‑gen CPUs, broader chip compatibility, GPU enhancements, and gaming peripherals like Nintendo Switch 2 and Valve Steam Frame VR headset.

Early compatibility extends to AMD Ryzen Zen 6 and Intel Panther Lake, plus GPUs and devices such as Nintendo Switch 2 controllers, with wider chipset support across Snapdragon, Apple M4 and Google Tensor G5.

Memory management advances include dynamic capacity LCD/CLC (CXL) preparations for dynamic memory expansion, faster boot-time physical memory allocator, workqueue and slab updates, the Core MM tree, and the sunset of some EDAC drivers to reduce maintenance.

The piece argues for a balance between stability and security, noting many users prefer long-term stable releases and backporting is essential to keep security up to date without sacrificing reliability.

Hardware and driver implications are significant, as changes can affect GPUs, network cards, and storage controllers; rolling-release users may receive kernels weeks after final release.

Networking gains include faster TCP/IP processing, reduced wireless latency, and groundwork for Wi‑Fi 8 and hardware-accelerated packet scheduling.

Legacy cleanup removes the BFS file system and RTL8723BS Wi‑Fi driver to streamline the kernel and signal ongoing modernization.
