Linux 6.15 is there: what he really changes for HP laptops, the Bcachefs system and network performance

Version 6.15 of the Linux kernel is now available, after a last week of rather calm development … Apart from a bug report seriously serious to temporarily deactivate a function. Linus Torvalds, however, maintained the course, stressing that this continuous version on a stable line, marked by an avalanche of small corrections and targeted improvements on the pilot, material and subsystems.

Linux 6.15: more stable, better optimized for HP Zbook and faster with Bcachefs

Among the material improvements, Linux 6.15 is distinguished by better support for certain portable configurations. Owners of HP Zbook like the X360 studio Note an improved management of the micro cutting LED (mint), a discreet but essential function for confidentiality. Specific fixes have also been integrated for Lenovo Yoga Pro 7the Dell Chromebook, and even old models such as the Fujitsu LifeBook S2110, which finally recovers the management of shortcut keys.

Another striking point, the BCACHEFS file system – often presented as the spiritual heir of ZFS for Linux – receives an important update on Casefolding, a function that allows you to treat file names without taking the breakage into account. Translation: more reliable file searches on the volumes configured with this option.

And that’s not all: enthusiasts of high network performance will appreciate the progress of Io_Uring, an asynchronous input/output mechanism which gradually becomes the reference for applications such as web servers, databases or simply optimized network transfers.

Linux 6.15 also prepares the field for the future: today opens the fusion window for Linux 6.16, even if the Memorial Day, in the United States, could slow down the first contributions. Linus, faithful to its line, still launched the sequence by ironically citing the USPS: “Neither snow, nor rain, heat, nor even Memorial Day will stop the Window Merge”. Well, except in the case of an ice storm …
