Kernel release status

[Posted January 22, 2025 by corbet]

The 6.13 kernel is out, released on January 19. As Linus put it: "So nothing horrible or unexpected happened last week, so I've tagged and pushed out the final 6.13 release."

Significant features in this release include the lazy preemption model for CPU scheduling, Arm64 Guarded Control Stack support, the PIDFD_GET_INFO() operation, multi-grain file timestamps, beginning atomic write support for the ext4 and XFS filesystems, the setxattrat(), getxattrat(), listxattrat(), and removexattrat() system calls, private stacks for BPF programs, a new mechanism for adding guard pages to a memory mapping, the removal of the reiserfs filesystem, and more. See the LWN merge-window summaries (part 1, part 2) and the KernelNewbies 6.13 page for more information.

Stable updates: 6.12.10, 6.6.72, and 6.1.125 were released on January 17, followed by 6.1.126 on January 19 and 6.6.73 on January 21.

The 6.12.11, 6.6.74, 6.1.127, and 5.15.177 updates are in the review process; they are due on January 23.
