Hi Herbert, apologies for the duplicate. The previous email didn't get delivered to the ML.

Are you suggesting to hide the scratch buffers from the scomp implementations and allocate them inside crypto_register_scomp? Does that mean we have to go back to a scomp_alg with a flat buffer API and linearize inside scomp? If we take this direction, how do we support DMA from scomp implementation? Scratch buffers are allocated using vmalloc.
