Linux 7.0 Merge Window Reaches Midpoint with 7,695 Commits Accepted

The Linux 7.0 kernel merge window is underway, and the midpoint summary reveals a busy first half: 7,695 non-merge commits have been accepted as of the halfway mark. Linux 7.0 was confirmed by Linus Torvalds following the release of Linux 6.19 on February 9, 2026, with a full stable release expected in mid-April 2026.

Rust Moves from Experiment to Established

Perhaps the most symbolically significant development in this merge window is the formal conclusion of what the kernel community had long called the "Rust experiment." With Linux 7.0, upstream kernel developers are now operating from a position of consensus: Rust in the Linux kernel is here to stay, and it is no longer treated as a provisional or experimental track.

A substantial portion of driver core changes in this window directly expand the infrastructure available for Rust-based kernel drivers. New abstractions and bindings have been merged to make writing and maintaining Rust drivers more practical, lowering the barrier for contributors working outside the traditional C-only path.

close_range Gets a Major Performance Boost

Linux 7.0 also delivers substantial optimizations to the close_range system call, which is used to efficiently close ranges of file descriptors in bulk. The improvements include:

• Enhanced batch processing that reduces internal kernel operations per call
• Reduced lock contention, allowing more concurrent file descriptor cleanup across processes
• More intelligent memory allocation during batch operations

These changes benefit workloads that frequently spawn and tear down large numbers of file descriptors — a common pattern in container runtimes, web servers, and process supervisors.

Looking Ahead

The merge window is expected to close with the release of Linux 7.0-rc1 around February 22, 2026. The full release is projected for mid-April. The commit volume and breadth of changes make this one of the more active merge windows in recent kernel history, continuing the trend of accelerating Rust adoption alongside steady performance improvements across core subsystems.
