Actually, I thought using CRYPTO_ALG_ASYNC in the mask meant to
_exclude_ asynchronous algorithms.

Is there any documentation for Linux crypto API that documents use of
CRYPTO_ALG_ASYNC?  Also, I'd like to know meanings of
CRYPTO_TFM_REQ_MAY_BACKLOG and CRYPTO_TFM_REQ_MAY_SLEEP.

The crypto API feels like a minefield to me - I should check everything
in the code or even experiment to figure out how the public API works.
