Please try again. I just rebuilt and uploaded the zfs-2.1.6 RPMs for RHEL 9.

Sorry, I read too fast and assumed that was coming from our kmod packages. I see you're building the kmods from scratch. Coincidentally, RHEL 9.1 just came out and I had to rebuild our kmod RPMs for it.

It's possible that RHEL 9 is still backporting a bunch of old kernel interfaces that ZFS autodetects and uses, rather than the newer, native ones. Seeing as we can build zfs-2.1.6 on the 6.0 kernel, it's probably reasonable to assume that if RHEL deprecates support for these older interfaces that we'll still be able to build zfs.
