Done for v5. The SHA-2/SHA-3/SHAKE, SM3 and cSHAKE ahash drivers now set CRYPTO_AHASH_ALG_BLOCK_ONLY and let the Crypto API buffer partial blocks (modelled on drivers/crypto/aspeed). The hand-rolled holdback is gone. Since BLOCK_ONLY's buffering is scatterlist-based, these drivers also drop CRYPTO_ALG_REQ_VIRT. cSHAKE stays cra_blocksize 1 as an XOF, so the HC core buffers the sub-rate remainder across its context save/restore. Thanks, Alex
