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.
