Comment 5 for bug 1969482

I've set up proposed and installed following. It does NOT work as expected.

I used following command to install zfs / kernel packages and dependencies and it resulted in installation / upgrade of packages mentioned below.

apt install zfsutils-linux zfs-initramfs zfs-zed linux-generic linux-image-generic-hwe-22.04 linux-firmware linux-generic-hwe-20.04

Install:

linux-firmware:amd64 (20220329.git681281e4-0ubuntu3, 20220329.git681281e4-0ubuntu3.2)

Then I got following system after reboot

root@XXX:~# uname -a
Linux nas139 5.15.0-33-generic #34-Ubuntu SMP Wed May 18 13:34:26 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

root@XXX:~# zfs --version
zfs-2.1.4-0ubuntu0.1
zfs-kmod-2.1.2-1ubuntu3

I still have old zfs-kmod a still very low ZFS performance on encrypted filesystem.
Did I do something wrong or there is missing updated zfs-kmod?
