I'm not sure what you're building, but this isn't latest master.

The packaged version of zfs 2.2.6 works just fine for me with the 6.10.6-200.fc40.x86_64 kernel on Fedora 40. What doesn't work for me is the same version of zfs with a 6.11 kernel on Fedora 41 beta, but that isn't surprising. I do see signs of 6.11 support in master.
