Encryption feature not enabled

[ptthon]

zfs version is:
zfs-0.8.6-1
zfs-kmod-0.7.5-1ubuntu16.12

According to the following steps to create the encrypted volume,but could not create volume
① To install the following commands to compile the installation ZFS
sudo tar -xvzf zfs-0.8.6.tar.gz
sudo cd zfs-0.8.6
sudo ./configure
sudo make
sudo make install
② truncate -s 100G /tmp/disk.img
zpool create zfspv-pool sudo losetup -f /tmp/disk.img --show

③ zfs create -o encryption=on -o keyformat=passphrase -o keylocation=prompt zfspv-pool/enc
the error is : cannot create 'zfspv-pool/enc': Encryption feature not enabled.

④ I try to execute the following commands,but still cannot create encrypted volume
zpool set feature@encryption=enabled

My guess is that zfs-kmod-0.7.5-1ubuntu16.12 needs to be upgraded to match zfs-0.8.6-1: Your kernel module is too old to know of the encryption feature. Please refer to the Ubuntu help channels for further advice as this does not appear to be an issue with zfs itself and its maintainers won't be able to change anything about how Ubuntu packages/ships zfs.

Thank you very much, I update the zfs-kmod, would be great
