Linus Torvalds released the 7.2 kernel on August 17, calling the number of fixes 'bigger than I would have wished for.' The release added nearly 600,000 lines of code, making it one of the busiest development cycles in kernel history. With 16,418 non-merge commits, 7.2 exceeded the already busy 7.1 release and became the second-busiest in kernel history, only behind 6.7. Unlike 6.7, which was dominated by the bcachefs merge, 7.2’s growth was broad-based across subsystems.
A record 2,652 developers contributed commits, up from 2,479 in 7.1. Developer participation has steadily increased over the Git era, though the rate of growth has slowed. Uwe Kleine-König led in commit count with cleanups in the driver subsystem, while Rosen Penev contributed numerous LLM-authored bug fixes across multiple areas. Ian Rogers and Arnaldo Carvalho de Melo focused on the user-space perf tool, and Johan Hovold improved SPI and USB subsystems.
Matthew Stewart topped the lines-changed list by adding massive amdgpu header files, a trend also seen with Hawking Zhang. Miguel Ojeda integrated the Rust zerocopy crate, and Darren Ye added the MediaTek mt8196 sound driver. Just over 8% of commits had Tested-by tags, and 48% had Reviewed-by tags — both showing a mild downward trend. Top testers included Dan Wheeler and Luiz Capitulino, while Konrad Dybcio led in review credits.
