Linux 6.12, designated as the latest Long-Term Support kernel, has officially merged the PREEMPT_RT real-time scheduling patch set into the mainline kernel after over 20 years of development.
Highlights
- PREEMPT_RT Mainlined — Real-time scheduling is now a configuration option in the standard kernel, no patches required
- Rust Drivers — More Rust-based device drivers, including the first Rust-based network driver
- Bcachefs Improvements — Better stability and performance for the Bcachefs filesystem
- io_uring Updates — New io_uring operations for zero-copy networking
System administrators and DevOps teams running LTS kernels should consider upgrading for improved scheduling performance and security patches.
