The latest Linux Kernel 6.10 Release Candidate (RC4) is here! This pre-release version brings many bug fixes and improvements, particularly for Bcachefs and cachefiles. Developers and enthusiasts can test RC4 to identify any potential issues before the final stable release.

On June 16th, Linus Torvalds, the principal developer of the Linux kernel, released the fourth release candidate (RC4) for the upcoming version 6.10 of the Linux kernel.

In his announcement on the Linux Kernel mailing list, he provided an overview of the changes and fixes included in this pre-release version.

Linus noted that while the diffstat (a summary of changes) showed an unusual spike due to a fix for the parisc architecture, the overall changes were relatively small and within normal expectations for a release candidate. As usual, the bulk of the changes consisted of driver fixes spread across various subsystems.

One notable change was a fix to the vfio pci memory mapping code, which actually removed more lines of code than it added. This fix likely addressed a memory management issue related to the Virtual Function I/O (VFIO) framework, which enables safe and efficient device access from userspace.

Another change that contributed to the diffstat spike was an update to the tracepoint implementation for the FireWire subsystem. Tracepoints are instrumentation points in the kernel code that aid in debugging and performance analysis.

Outside of the driver changes, the release candidate included some more fixes for the bcachefs filesystem. Bcachefs is a next-generation file system that aims to improve upon existing Linux file systems. It's worth noting that the Linux Kernel RC2 also included many fixes for bcachefs, highlighting the ongoing development and stabilization efforts for this new filesystem.

The RC4 release also addressed issues in the cachefiles subsystem, which is a caching backend used by certain filesystems to improve performance.

The remaining changes were described as small and scattered across various kernel subsystems, reflecting the typical makeup of a release candidate.

For those interested in exploring the details, Linus Torvalds provided a shortlog, which is a condensed summary of the individual commits included in the release.

Overall, this release candidate focused on stabilizing the upcoming 6.10 kernel release by addressing driver issues, filesystem bugs (particularly in bcachefs), and miscellaneous improvements across the kernel codebase.

Test Linux Kernel 6.10 RC4

Users are encouraged to test the latest release candidate by downloading it from the Kernel.org website or the Linus Torvalds's git tree.

Please note that these development versions should not be used on production systems due to their experimental nature.
