Linux 7.4 Merge Window Records 19,671 Commits
Linux 7.4 recorded 19,671 commits during its merge window, setting a new record for the highest volume of activity since the release of Linux 3.1.
Linux 7.4 recorded 19,671 Git commits ahead of its expected 7.4-rc1 release, marking the largest merge window since Linux 3.1 in 2011. This total surpasses the previous high of 16,267 set by Linux 7.3.
Merge windows typically contain 13,000 to 14,000 commits or fewer. Prior to the recent pair of releases, the largest historical windows were Linux 6.7 at 16,203, Linux 4.9 at 15,095, and Linux 5.8 at 15,086. The progression across recent versions shows steady growth, moving from 12,468 in Linux 7.0 and 13,963 in Linux 7.1 to 14,395 in Linux 7.2. Michael Larabel compiled these figures, noting that AI and large language model activity drives much of the increase.
Kernel maintainers report being completely overwhelmed by AI-generated bug reports, patches, and fixes. Linux's broader popularity across consumer devices and data centers is also a contributing factor. Because AI-driven workloads heavily involve fixes, the high volume persists past the merge window. Linux 7.3 became the first release to exceed 20,000 total commits across a full development cycle, logging 20,260 between versions v7.2 and v7.3. Linux 7.4 nearly matched that full-cycle count during its merge window alone, pushing the kernel source tree close to 42 million total lines and increasing the review and integration load for maintainers.
