Linux 7.0 kernel来了
Linux 7.0：内核新特性及代际飞跃
⚡ 跳过6.20直奔7.0！Linus Torvalds的"手指计数"传统再续，性能飞跃超乎想象
Linux 7.0 代表着一次重大的技术飞跃：内核采用 Rust 语言，移除了 HIPPI 等过时的代码，并引入了新的缓存层。
默认采用 Intel TSX、时间片扩展，并针对下一代 CPU 和 GPU 进行精细化支持，从而提高性能和效率。
利用 Bcachefs、加密内存隔离区和改进的云中虚拟机隔离来增强安全性和可靠性。
它作为 Ubuntu 26.04 LTS 等主要发行版的基础，具有更好的硬件兼容性、HDR/VRR 图形和更完善的桌面体验。
