[bugcrazy]

System information

Type	Version/Name
Distribution Name	Void Linux
Distribution Version	Rolling release
Kernel Version	6.0.8
Architecture	x86_64
OpenZFS Version	2.1.6

Describe the problem you're observing

Xanmod rt versions do not compile OpenZFS module, non rt versions compile normally, the same problem occurs on Ubuntu.

Describe how to reproduce the problem

In Void Linux you need to use this repository to create kernel:
https://notabug.org/Marcoapc/voidxanmodK

On Ubuntu you need to follow the steps from the official Xanmod website:
https://xanmod.org/

As there are no failed build logs, I can only assume it to be the same issue that plagues all kernels that apply the rt kernel patches: relicensing of the kernel symbols migrate_enable and migrate_disable to be GPL only.

Looks like a duplicate of #11097 to me.

Or, the zfs version is just too old for the kernel version:
zfs-2.1.6
Supported Platforms

Linux: compatible with 3.10 - 5.19 kernels
