From f2ffe5a9183d22eec718edac03e8bfcedf4dee70 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 16 Feb 2025 11:07:17 +0800 Subject: crypto: hash - Add request chaining API This adds request chaining to the ahash interface. Request chaining allows multiple requests to be submitted in one shot. An algorithm can elect to receive chained requests by setting the flag CRYPTO_ALG_REQ_CHAIN. If this bit is not set, the API will break up chained requests and submit them one-by-one. A new err field is added to struct crypto_async_request to record the return value for each individual request.
