43 * Crypto driver method to initialize a new session object with the given
44 * initialization parameters (cryptoini). The driver's session memory object
45 * is already allocated and zeroed, like driver softcs. It is accessed with
46 * crypto_get_driver_session().

55 * Optional crypto driver method to release any additional allocations. OCF
56 * owns session memory itself; it is zeroed before release.
