Linux 7.0: Large-Scale Optimization and Farewell to Legacy Architecture

Linus Torvalds announced the release of the anniversary version of the Linux 7.0 kernel. The main feature of the update is a large-scale revision of outdated code: a huge amount of “legacy” code that slowed down system development has been removed. As a result, the architecture has become lighter, more reliable, and more efficient.

Optimization of XFS and Data Handling

The stability of XFS has become one of the main focuses of the new release. 

• Updated mechanisms allow the file system to perform self-diagnostics and fix errors in real time, which practically eliminates the risk of data loss.
• Additionally, optimization of the memory management subsystem has resulted in a speed increase of up to 20%. This has also improved network stability under extreme loads.

Architectural Changes

Several important architectural changes have been implemented for developers and system administrators.

• Thanks to a new flag in the open_tree system call, deploying isolated environments, particularly containers, has become almost instantaneous.
• Also, the classic penguin logo can now be replaced with any custom image via Kconfig parameters.

Component Performance Freedom

Owners of modern AMD and Intel chips will notice increased performance without manual tuning. New algorithms allow processors to distribute resources more efficiently, providing a noticeable boost in power.
