Linux 5.19 compatibility

[hmenke]

Describe the feature would like to see added to OpenZFS

Please make a release with the Linux 5.19 compatibility patches merged in and

Linux-Maximum: 5.19

in META. Right now some downstream consumers like the NixOS Linux distributions are in limbo because 5.18 is EOL and is being removed and 5.19 is not yet supported by ZFS.

How will this feature improve OpenZFS?

Easier integration for rolling-release bleeding-edge Linux distributions.

It is coming soon. See #13886.

@hmenke If you really need something now (like I did for my new Lenovo laptop which requires at minimum 5.18.x it seems), this patch worked for me today (I would attach the *.patch file, but Microsoft GitHub does not support this).

What about 6.0?

[behlendorf]

The needed patches for 6.0 are in the 2.1.6 release. However, the final version of 6.0 was released about the same time as 2.1.6 so it's less tested. If you update the META file from 5.19 to 6.0 it should build.
