If you integrate it to kernel crypto-api, it will be used automatically
when this module loads and the aes-xts mode is used in the mapping.

(Current crypt providers/drivers with it usage priorities are visible
in /proc/crypto - kernel prefers optimized drivers before generic one this way).

Ask on linux-crypto@vger.kernel.org mailing list how to do that properly.
