Just search for crypto_ahash_set_reqsize in drivers/crypto and see
how they use the reqctx to store temporary data.  For each request,
you're guaranteed to have exclusive ownership of the reqctx.

If you wish to DMA into the reqctx, search for ahash_request_ctx_dma
to see how you should set it up.

Cheers,
