- * DOC: Asynchronous Block Cipher API
- *
- * Asynchronous block cipher API is used with the ciphers of type
- * CRYPTO_ALG_TYPE_ABLKCIPHER (listed as type "ablkcipher" in /proc/crypto).
- *
- * Asynchronous cipher operations imply that the function invocation for a
- * cipher request returns immediately before the completion of the operation.
- * The cipher request is scheduled as a separate kernel thread and therefore
- * load-balanced on the different CPUs via the process scheduler. To allow
- * the kernel crypto API to inform the caller about the completion of a cipher
- * request, the caller must provide a callback function. That function is
- * invoked with the cipher handle when the request completes.
- *
- * To support the asynchronous operation, additional information than just the
- * cipher handle must be supplied to the kernel crypto API. That additional
- * information is given by filling in the ablkcipher_request data structure.
- *
- * For the asynchronous block cipher API, the state is maintained with the tfm
- * cipher handle. A single tfm can be used across multiple calls and in
- * parallel. For asynchronous block cipher calls, context data supplied and
- * only used by the caller can be referenced the request data structure in
- * addition to the IV used for the cipher request. The maintenance of such
- * state information would be important for a crypto driver implementer to
- * have, because when calling the callback function upon completion of the
- * cipher operation, that callback function may need some information about
- * which operation just finished if it invoked multiple in parallel. This
- * state information is unused by the kernel crypto API.
