OpenZFS 2.1.5 Released With Linux 5.18 Compatibility, Bug Fixes
OpenZFS 2.1.5 is mostly about fixing up bugs but does have Linux 5.18 compatibility updates so this latest stable kernel is now officially supported while retaining support back through Linux 3.10. There are also some patches in this release for Linux 5.19 compatibility, which is still in the release candidate phase and thus still subject to possible breakage prior to the stable release next month. In any event the Linux 5.19 compatibility may play out or at least they have a start on this next kernel version. OpenZFS 2.1.5 for FreeBSD systems continues working with FreeBSD 12.2-RELEASE and newer.
OpenZFS 2.1.5 also brings improved sorted scan memory accounting, a few Red Hat Enterprise Linux targeted changes, hole punching support on FreeBSD, and various other fixes.
