Sorry for the noise. =================== This patch set implements a bit different approach to shared tfm. It defines a new CRYPTO_ALG_TFM_MAY_SHARE ->cra_flag which each algorithm setups in its `static struct crypto_alg'. Crypto API provides crypto_tfm_may_share() function that returns true if the algorithm has CRYPTO_ALG_TFM_MAY_SHARE set and, thus, we can supply a shared `struct crypto_comp *tfm'. Not properly tested yet.
