OpenZFS 2.2.6 Debuts With Linux 6.10 Support & Early Linux 6.11 Compatibility
OpenZFS 2.2.6 was released this evening and now officially supports from Linux 4.18 up through the Linux 6.10 stable series. Linux 6.10 support is new with the v6.10 support being incomplete in the prior OpenZFS 2.2.5. We are just roughly two or so weeks out from the Linux 6.11 stable kernel release and this updated OpenZFS out-of-tree code does have some initial kernel compatibility support for that next kernel release.
A number of patches in OpenZFS 2.2.6 work on the Linux 6.11 compatibility but it remains to be seen if it will be good enough by the time Linux 6.11 rolls out as stable given the lack of API/ABI guarantees for the upstream Linux kernel. At least though Linux 6.10 is now fully supported. FreeBSD 12.2-RELEASE and newer remain fully supported by upstream OpenZFS.
OpenZFS 2.2.6 also now enables L2 cache on all MRU+MFU meta-data in L2ARC and a variety of various fixes.
