Linux Kernel 7.2 released with cache-aware scheduling

Linus Torvalds has released Linux kernel version 7.2. This update introduces several architectural and performance improvements, including cache-aware task scheduling designed to co-locate tasks sharing data within the same Last Level Cache domain to reduce cache misses.

The release includes significant updates to SELinux, addressing issues with TCP Fast Open socket permissions, overlayfs filesystem credential checks, and inode initialization in bpffs. Additionally, the audit subsystem received fixes for potential race conditions, integer overflows in large audit records, and use-after-free vulnerabilities.

While the release contains many small fixes across drivers and networking, it also required the reversion of a DRM scheduler change due to serious GPU regressions. The merge window for Linux 7.3 has already opened following this release.
