Linus Torvalds prepares to ship Linux 7.2. The kernel stands at more than 43 million lines. That figure comes straight from Phoronix’s feature overview. And the code keeps growing. Even as old sections get removed.
Developers merged substantial changes during the merge window that closed in late June. Cache aware scheduling tops the list for many. The new logic places related tasks on CPU cores that share cache levels. Modern Intel and AMD processors benefit directly. Task placement decisions now factor in cache topology. Performance follows.
But the headlines don’t stop at scheduling. USB4STREAM delivers a clever way to move data between two systems over USB4 or Thunderbolt cables. No network stack required. Just direct transfers. Apple M3 systems can now boot on mainline code. Practical use remains limited. Still, the foundation sits in place.
AMD’s ISP4 driver finally lands. Webcams on certain HP ZBook laptops and similar hardware gain support. AMDGPU picks up initial HDMI 2.1 FRL capability. Full HDMI 2.1 remains ahead. This step advances toward it. Phoronix flags these as among the most visible end-user wins.
Memory management receives attention too. The MGLRU implementation shows striking gains. MongoDB throughput climbs 30 to 100 percent in targeted tests. Other optimizations speed up poll and local networking paths. Container start times drop. Slab allocation gets tighter. Anonymous pipe handling improves. Even reads from the /proc filesystem accelerate dramatically. One workload sees up to 444 percent faster results.
AI Reshapes the Release Process Itself
Late in the cycle the volume of changes raised eyebrows. Linux 7.2-rc7 arrived packed with fixes. More than four hundred in one week. Over two hundred developers signed off. Torvalds sounded candid. “I can’t say that I’m exactly thrilled about the size of this all, but it is what it is: the new normal with a lot of fixes, many of them due to review by various AI tools,” he wrote in the rc7 announcement, as reported by The Register.
He noted nothing looked especially dangerous. Most patches stayed small. A few stood out. S390 zcrypt fixes. Btrfs restoring its fixup worker infrastructure to prevent silent data loss. Netfilter ipset corrections. Fixes touched drivers, filesystems, networking, and architecture code alike. Torvalds saw no reason to delay. Stable 7.2 should drop this weekend barring major trouble. The date: August 16, 2026.
AI tools reviewed code and flagged issues. Networking saw a wave of AI-generated patches. Hardware monitoring caught several critical and high-severity bugs. Memory management fixed an eight-year-old race that could cause use-after-free errors. The kernel also gained protection against the Safe RET Interrupt Vulnerability.
Yet not every change survived. The DRM scheduler switched to a “fair” policy early in the cycle. Tvrtko Ursulin at Igalia led the work. The goal was better balance across AMDGPU and other graphics drivers. Real-world use exposed problems. One user reported severe performance drops on an RX 9070 XT. Sustained 100 percent GPU load during games caused foreground applications to fall to roughly 10 frames per second or freeze. Background gaming plus a YouTube video could lock the entire KDE Plasma Wayland session. Reboot or compositor kill became necessary.
Ursulin sent twenty revert patches. Linux 7.2 returns to the older FIFO scheduler. The team will investigate the regression with more time. Phoronix covered the reversal. The episode shows how last-minute reports can still reshape a release this close to the finish line.
Other hardware work continues. Preparations for AMD Zen 6 appear. EDAC support expands to Intel’s Diamond Rapids and Nova Lake. RISC-V trims startup overhead and makes ESWIN the default in some places. ARM64 gains NEON-accelerated CRC64. The i486 architecture moves closer to removal. Intel TDX sees runtime updates that avoid reboots. Power management receives incremental lifts across platforms.
Graphics stay busy. AMDGPU improves display core power management. More AMD IP blocks gain support. Intel readies code for Crescent Island. Nouveau adds GA100 coverage. NVIDIA Blackwell preparation advances. DRM subsystem tweaks accumulate.
The kernel also sets new guidelines to curb filesystem proliferation. Future additions face stricter review. This aims to keep the tree manageable as hardware and use cases multiply.
Ubuntu 26.10 plans to ship 7.2 as its default kernel. Other distributions will follow in coming months. For server operators the scheduling and memory gains matter most. Desktop users notice better hardware support and smoother graphics.
Torvalds has mixed feelings about the AI assistance. He accepts the volume it produces while watching patch quality. The “new normal” comment suggests this pace may persist. Larger release candidates. More automated review. Faster bug hunting. The question is whether human oversight keeps pace.
So Linux 7.2 brings tangible improvements. Cache-aware placement. Faster containers. Stronger hardware enablement. And a release process increasingly shaped by machine intelligence. The code base swells past 43 million lines. Stability holds. Users will soon test the results in production.
