I agree we should not have failed requests, _with_ MAY_BACKLOG, that pass through crypto-engine. All these requests must me executed.

For non-crypto API requests (like split key or rng) I cannot pass them through crypto-engine which only supports aead, skcipher, hash and akcipher requests. So, I believe that if the first problem is solved (to have all crypto API requests, that have backlog flag executed - retry mechanism instead of reporting failure) the non-crypto API request doesn't have to be pass through crypto-engine - these can be handled by driver.
