Linux Kernel 6.10 RC4 Released With More Bcachefs And Cachefiles Fixes

Linux Kernel 6.10 RC4 release: Fix issues such as Bcachefs and cachefiles

Linus Torvalds, the lead developer of the Linux kernel, released the fourth version of the upcoming 6.10 version (RC4) on June 16.

In the announcement of the Linux kernel mailing list, he outlined the changes and fixes included in this pre-release release.

Linus noted that while diffstat (change summary) showed abnormal peaks due to fixing the parisc architecture, the overall change was relatively small and was consistent with the normal expectations of the candidate version. As usual, most of the changes include driver fixes distributed across subsystems.

One notable change is the fix of the vfio pci memory mapped code , which actually deletes more lines of code than added. This fix may address memory management issues related to the Virtual Function I/O (VFIO) framework that supports secure and efficient access to devices from user space.

Another change that caused the diffstat peak was the update of the tracking point implementation of the FireWire subsystem. Tracking points are detection points in kernel code that facilitate debugging and performance analysis.

In addition to driver changes, the candidate version includes more fixes for the bcachefs file system . Bcachefs is a next-generation file system designed to improve existing Linux file systems. It is worth noting that the Linux kernel RC2 also includes many fixes for bcachefs, highlighting the continuous development and stable work of this new file system.

The RC4 version also addresses issues in the cachefiles subsystem, a cache backend used by some file systems to improve performance.

The remaining changes are described as small changes scattered across the individual kernel subsystems, reflecting the typical composition of the candidate version.

For those interested in exploring the details, Linus Torvalds provides a shortlog, which is a brief summary of a single commit included in this release.

Overall, this version candidate focuses on stabilizing the upcoming 6.10 kernel version by addressing driver issues, file system errors (especially in bcachefs), and various improvements in the kernel code base.

Test Linux kernel 6.10 RC4

Users are encouraged to download the latest version candidates from the Kernel.org website or Linus Torvalds git tree for testing.

Note that these development versions should not be used in production systems because they are experimental.
