To simplify maintenance and system administration, sys-fs/zfs-kmod has been
merged into sys-fs/zfs starting from version 2.4.0_rc2-r1.
If you are using in-kernel modules from a custom built kernel you should unset the modules USE flag for sys-fs/zfs to not build and install kernel modules via sys-fs/zfs.
If you were using sys-fs/zfs-kmod and sys-fs/zfs before, you have not to do anything special while upgrading as the package manager will take care of deinstalling sys-fs/zfs-kmod before upgrading to the new sys-fs/zfs version containing the modules.
If you experience a blocker, you may have to remove sys-fs/zfs-kmod from your world file by running
