Linux kernel 7.2 release and scheduling updates

Overview

The release of the Linux 7.2 kernel introduces cache-aware scheduling (CAS) to improve performance on modern multi-socket servers and many-core processors. By recognizing Last-Level Cache (LLC) topology, the scheduler co-locates threads that share data to reduce cache misses and bouncing.

Performance reports indicate significant gains; for example, Hygon reported up to a 360% increase in transactions per second for MySQL workloads when extending this scheduling. Other updates in the 7.2 release include security hardening to eliminate kernel bugs and the stabilization of large folios in Btrfs.

In the broader ecosystem, the Liquorix Linux Kernel 7.2-13 has been released as a maintenance update merging upstream 7.2.8. Additionally, developers have noted a “new normal” in kernel development due to an increase in patch submissions generated by AI tools.
