Linux 6.17 Now Makes Multi-Core/SMP Support Unconditional • Phoronix

｢ The patches standardize the Linux scheduler on the Symmetric Multi-Processing (SMP) to avoid unnecessary complexity and obstacles with the non-SMP patches likely never used but posing a maintenance and complexity burden on kernel developers ｣

Now running #Linux #kernel 6.15.8.

Linux 6.16 bringt entspannte Leistungssteigerungen: USB Audio Offloading spart Energie & verlängert Akkulaufzeit , CPU-seitig optimiert mit X86_NATIVE_CPU für maximale Performance . Verbesserungen für Intel, AMD, Nvidia & Apple Silicon machen den Kernel fit für viele Systeme! #Linux #Kernel #Tech https://www.heise.de/news/Linux-6-16-Entspannt-zu-mehr-Leistung-10503711.html

Linux 6.16 disponibile

Nonostante il cuore del kernel rimanga saldamente in C, Rust sta facendo passi da gigante con nuove integrazioni. Ora abbiamo binding Rust per il driver core e il sottosistema PCI. Inoltre, porta anche nuove astrazioni nel DRM, migliorando la gestione della memoria e riducendo le vulnerabilità. Mi aspetto, di conseguenza, prestazioni grafiche meglio ottimizzate per GPU di #AMD, #Nvidia e #Intel.

Vediamo.

Some highlights from various #VFS merges for #Linux 6.17 where @brauner submitted the PR:

https://git.kernel.org/torvalds/c/278c7d9b5e0ca73a75e5151c22fb05c91cb4495f: fallocate() updates bringing support for the BLK_FEAT_WRITE_ZEROES_UNMAP feature and BLK_FLAG_WRITE_ZEROES_UNMAP_DISABLED flag for SCSI, NVMe and device-mapper drivers, and add the FALLOC_FL_WRITE_ZEROES and for ext4 and raw bdev devices; this enables preventing numerous metadata changes and journal I/O, which may lead to significant write amplification and performance degradation in synchronous write mode.

https://git.kernel.org/torvalds/c/57fcb7d930d8f00f383e995aeebdcd2b416a187a: support for the the new file_getattr() and file_setattr() system calls (after lengthy discussions), which allow userspace to set filesystem inode attributes on special files (One of the usage examples is the XFS quota projects.)

https://git.kernel.org/torvalds/c/7879d7aff0ffd969fcb1a59e3f87ebb353e47b7f: ext4 IOCB_DONTCACHE support

https://git.kernel.org/torvalds/c/117eab5c6e31815649d952f6da03f67aa247d29b: An extension to the coredump socket and a proper rework of the coredump code.

Linux 6.16 è disponibile: performance, sicurezza, architetture e nuove funzionalità

""[…] This blog post discusses atomic commit of file contents [in #XFS #Linux 6.13+]. In this context, the difference between “commit” and “exchange” is that the commit system call exchanges the two files’ contents only if the target file has not been modified since a past point in time.

[…]

Conclusion

As you have seen, it is now possible to commit a collection of arbitrary file updates to a file if that file has not been updated, and expect that readers see either the old version or the new version.""

Some excellent #Ubuntu themed updates over the past couple of days!

First, a write up of the progress on our TPM-backed full disk encryption efforts in preparation for the LTS release cycle: https://discourse.ubuntu.com/t/tpm-fde-progress-for-ubuntu-25-10/65146.

I was also delighted to see our #kernel team step up their commitment on release cadence to get newer kernels shipped and tested faster in line with our new monthly snapshot releases: https://discourse.ubuntu.com/t/kernel-development-release-cadence-and-deprecation-of-linux-modules-extra/65176.

And finally... the latest edition of the Ubuntu Server Gazette discussing software "freshness" and how to get an experience closer to that of a rolling release with Ubuntu: https://discourse.ubuntu.com/t/ubuntu-server-gazette-issue-6-an-extra-fresh-rolling-ubuntu-please/65190

Enjoy!

Highlights from the main #NFSd merge for #Linux 6.17[1]:

""NFSD is finally able to offer write delegations to clients that open files with O_WRONLY, thanks to patches from Dai Ngo. We're expecting this to accelerate a few interesting corner cases.

The cap on the number of operations per NFSv4 COMPOUND has been lifted.[…]

This release re-enables the ability for NFSD to perform NFSv4.2 COPY operations asynchronously. […]""

Highlights from the main #erofs (used by #composefs) merge for #Linux 6.17[1]:

""We now support metadata compression. It can be useful for embedded use cases or archiving a large number of small files.

Additionally, readdir performance has been improved by enabling readahead (note that it was already common practice for ext3/4 non-dx and f2fs directories). We may consider further improvements later toalign with ext4's s_inode_readahead_blks behavior for slow devices too.""

Neue Regeln für KI-Code im Kernel
https://linuxnews.de/neue-regeln-fuer-ki-code-im-kernel/ #kernel #ki #ai #linux

From the main #ntfs3 merge for #Linux 6.17[1]:

"Added:
- sanity check for file name
- mark live inode as bad and avoid any operations

Fixed:
- handling of symlinks created in windows
- creation of symlinks for relative path

Changed:
- cancel setting inode as bad after removing name fails
- revert 'replace inode_trylock with inode_lock'"

Highlights from the main #btrfs merge for #Linux 6.17[1]:

A number of usability and feature updates, scattered performance improvements and fixes. Highlight of the core changes is getting closer to enabling large folios (now behind a config option).

[…]

Performance improvements:

- caching of lookup results of free space bitmap (20% runtime improvement on an empty file creation benchmark)

- accessors to metadata (b-tree items) simplified and optimized, minor improvement in metadata-heavy workloads

- readahead on compressed data improves sequential read

- the xarray for extent buffers is indexed by denser keys, leading to better packing of the nodes (50-70% reduction of leaf nodes)
