+/**
+ * struct acomp_alg - asynchronous compression algorithm
+ *
+ * @compress:	Function performs a compress operation
+ * @decompress:	Function performs a de-compress operation
+ * @dst_free:	Frees destination buffer if allocated inside the algorithm
+ * @init:	Initialize the cryptographic transformation object.
+ *		This function is used to initialize the cryptographic
+ *		transformation object. This function is called only once at
+ *		the instantiation time, right after the transformation context
+ *		was allocated. In case the cryptographic hardware has some
+ *		special requirements which need to be handled by software, this
+ *		function shall check for the precise requirement of the
+ *		transformation and put any software fallbacks in place.
+ * @exit:	Deinitialize the cryptographic transformation object. This is a
+ *		counterpart to @init, used to remove various changes set in
+ *		@init.
+ *
+ * @reqsize:	Context size for (de)compression requests
+ * @stat:	Statistics for compress algorithm
+ * @base:	Common crypto API algorithm data structure
+ * @calg:	Cmonn algorithm data structure shared with scomp
