Linux 7.0 Kernel Released with Revolutionary Scheduler and Rust Drivers

Linus Torvalds has announced the release of Linux kernel 7.0, the most significant kernel update in years. The release features a completely rewritten process scheduler, first-class Rust driver support, and major improvements to container and virtualization performance.

Major Changes

1. New EEVDF Scheduler V2

The Earliest Eligible Virtual Deadline First scheduler has been completely rewritten for better performance on modern hardware:

• 30% better latency for interactive workloads
• Native support for heterogeneous CPU architectures (big.LITTLE)
• Improved energy efficiency on laptops (15% longer battery life)
• Better container isolation with per-cgroup scheduling policies

2. Rust in the Kernel

For the first time, production-quality Rust drivers are included in the mainline kernel:

• NVMe driver rewritten in Rust (memory-safe, same performance)
• New GPU driver framework in Rust
• Rust-based networking stack components
• Official Rust API documentation for kernel module development

3. Container Performance

# Benchmark results (operations per second)
Docker container creation:  Linux 6.x: 45/sec → Linux 7.0: 120/sec
Kubernetes pod startup:     Linux 6.x: 2.1s  → Linux 7.0: 0.8s
cgroup memory accounting:   Linux 6.x: 5% overhead → Linux 7.0: 1.2%

What Developers Should Know

• If you run containers in production, upgrade for significant performance gains
• Rust developers can now write kernel modules - a new frontier for systems programming
• The new io_uring improvements make async I/O even faster for database workloads
• eBPF capabilities expanded for better observability without kernel modules

Upgrade Path

Major distributions are expected to adopt Linux 7.0: Ubuntu 26.04 LTS (included), Fedora 42 (included), and enterprise distributions within 6-12 months.
