openzfs 2.1.14 supports kernels up to 6.5.
The compat 6.6 patches are in the 2.2 releases.

[maximd1]

Thank you. Anyway, issue may be closed - I managed to build 2.2.2 from sources.

openzfs 2.1.14 supports kernels up to 6.5. The compat 6.6 patches are in the 2.2 releases.

Do you happen to know if openzfs 2.1.14 will support the 6.6 kernel?

[tw-atroehrsm]

Hey! Any chance to have compat changes for 6.6 merged into 2.1.15 staging?
giving that 6.6 is a LTS kernel it might make sense.. Me personally I'm still reluctant to move to 2.2 with all those changes going on there. currently im using 6.1 lts kernel

[behlendorf]

There's an open PR #15860 to backport these changes for 2.1.15-staging so they can be included in 2.1.15.
