Thanks.

I've converted the test vectors and generated patch below,
which is based on a previous patch you've sent:
https://lore.kernel.org/linux-crypto/MN2PR20MB29739591E1A3E54E7A8A8E18CAC00@MN2PR20MB2973.namprd20.prod.outlook.com/

Subject: [PATCH] crypto: testmgr - Add additional AES-XTS vectors for covering
 CTS (part II)

Add more test vectors (provided by Pascal Van Leeuwen)
for xts ciphertext stealing checking.

They are derived from the test vectors added in
commit "crypto: testmgr - Add additional AES-XTS vectors for covering CTS"
where IV / tweak was truncated to 8 bytes (and obviously
different ciphertext).
