For the encryption functionality in the ZFS filesystem we use AES in CCM
or GCM mode at the block level to provide confidentiality and
authentication. There is also a SHA256 checksum per block (of the
ciphertext) that forms a Merkle tree of all the blocks in the pool.
Note that I have to store the full IV in the block. A block here is a
ZFS block which is any power of two from 512 bytes to

we are later mounting the dataset we have a different in memory
dsl_dataset_t* referring to the same dataset.
This causes me a big issue with per dataset
