While OpenZFS 2.1.13 stable brought Linux 6.5 support recently, OpenZFS 2.2-rc5 picks up Linux 6.5 stable kernel support for the v2.2 series. OpenZFS 2.2-rc5 is working on Linux 3.10 through Linux 6.5 kernels plus FreeBSD 12.2 and later.
In addition to the Linux 6.5 kernel compatibility, OpenZFS 2.2-rc5 also has a number of bug fixes, more constraints for block cloning, and other preparations ahead of the OpenZFS 2.2 stable release that will hopefully happen soon.
The full list of OpenZFS 2.2-rc5 changes with the list of fixes and downloads for this open-source ZFS file-system source code can be found over on GitHub .
