Linux 6.13 changelog.

Summary:

1. Prominent features

1.1. Lazy preemption

The Linux kernel support four different preemption modes. There is a "full preemption" mode, but since preemption is usually at odds with performance, most Linux kernels default to using the "voluntary" mode.

This release adds a "lazy preemption" mode that aims to be a bridge between the voluntay and the full preemption mode, providing more opportunities to preempt a task than the voluntary mode, but not as many as the full preemption.

1.2. Support for multi-grain file timestamps: fine-grained timestamps, without the performance overhead

Some applications (notably, NFS) need higher-resolution timestamps on files, but higher resolution timestamps on all files can increase the rate at which metadata needs to be written to the disk. In this release, Linux adds support for fine-grained timestamps, but only when processes do query that information for a file. This allows for finer-grained timestamps without the performance overhead.

Documentation: Multigrain Timestamps

1.3. Support for atomic write operations

There is some hardware that supports atomic write operations, by which we mean writes to write data that is larger than the storage's sector size in an atomic way. This release adds support for atomic writes in XFS, Ext4's Direct I/O, and some md RAID modes.

2. Core (various)

• (FEATURED) Lazy preemption commit, commit, commit, commit

• cgroup: Exposing nice CPU usage to userspace commit, commit

• fanotify: allow reporting errors on failure to open fd commit

• fcntl: make F_DUPFD_QUERY associative commit

• fs/file.c: optimize the critical section of file_lock in commit, commit, commit

• Add the four syscalls setxattrat(), getxattrat(), listxattrat() and removexattrat(). Those can be used to operate on extended attributes, especially security related ones, either relative to a pinned directory or on a file descriptor without read access, avoiding a /proc/<pid>/fd/<fd> detour, requiring a mounted procfs. Part of a small-scale attempt at sanitizing the interplay between io_uring and normal syscalls commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• Introduce file_ref_t (for better scalability) commit, commit, commit, commit

• (FEATUREd) fs: multigrain timestamp commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• Allow statmount() to fetch the fs_subtype and sb_source commit, commit, commit, commit

• Use a dedicated thread for timer wakeups with forced-threading. commit, commit

• fs: Allow statmount to fetch the fs_subtype and sb_source commit, commit, commit, commit

• statmount: add flag to retrieve unescaped options commit

• statmount: retrieve security mount options commit

• Add API (AT_HANDLE_CONNECTABLE) for exporting NFS connectable file handles to userspace commit, commit, commit, commit

• futex: improve user space accesses commit

• hung_task: Add detect count for hung tasks commit, commit

• io_uring

  • Support for sending a sync message to another ring, without having a ring available to send a normal async message commit

  • Add support for ring resizing. It can be hard to appropriately size the CQ ring upfront, if the application doesn't know how busy it will be. This results in applications sizing rings for the most busy case, which can be wasteful. With ring resizing, they can start small and grow the ring, if needed commit, commit, commit, commit

  • Add support for fixed wait regions, rather than needing to copy the same wait data tons of times for each wait operation commit, commit, commit

  • Rewrite the resource node handling, which before was serialized per ring commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

  • Add static NAPI support, where a specific NAPI instance is used rather than having a list of them available that need lookup commit, commit, commit, commit, commit, commit

  • Regions, param pre-mapping and reg waits extension: it's a better and more generic API for ring/memory/region registration, and it changes the API extending registered waits to be a generic parameter passing mechanism. That will be useful in the future to implement a more flexible rings creation, especially when we want to share same huge page / mapping commit, commit, commit, commit, commit, commit

  • Add support for hybrid IO polling, which is a variant of strict IOPOLL but with an initial sleep delay to avoid spinning too early and wasting resources on devices that aren't necessarily in the < 5 usec category wrt latencies commit

  • Add support for just doing partial buffer clones, rather than always cloning the entire buffer table commit, commit

  • Limit local tw done commit, commit

• pidfd: add ioctl to retrieve pid info commit

12.2. Power Management

• Add thermal user thresholds support, which is a way to have the userspace to tell the thermal framework to send a notification when a temperature limit is crossed. There is no id, no hysteresis, just the temperature and the direction of the limit crossing. That means we can be notified when a threshold is crossed the way up only, or the way down only or both ways. That allows to create hysteresis values if it is needed. commit, commit, commit, commit, commit
