According to https://github.com/zfsonlinux/zfs/releases/tag/zfs-0.8.2, it is compatible with kernels up to 5.4, but emerge on a 5.4 kernel currently errors out because ZFS_KERNEL_COMPAT is set to 5.3. I confirmed that changing this to 5.4 in a local overlay compiles successfully against a 5.4 kernel. Reproducible: Always
I usually refer to this file to determine compatibility https://github.com/zfsonlinux/zfs/blob/zfs-0.8.2/META and it says 5.3 but yeah I see commit message says compatible up to 5.4 I'll need to investigate it a bit before bumping compat. There've been nasty bugs related to bumping compat in the past. also, ebuild contains a magic variable: ZFS_KERNEL_COMPAT_OVERRIDE you can use the following command ZFS_KERNEL_COMPAT_OVERRIDE=5.4 emerge zfs-kmod no need to copy ebuild to local overlay.
I just found Brian's comment here, which explains why the META says 5.3 while the release notes say 5.4: https://github.com/zfsonlinux/zfs/pull/9654#issuecomment-560537636

thanks for finding confirmation! rebvumped ebuild so everyone who have 5.4 kernel masked see the bump and unmask it.
