Subject: [PATCH v4 08/12] cryptodev: Use CryptoDevBackendOpInfo for operation
Date: Sun, 29 Jan 2023 10:57:43 +0800	[thread overview]
Message-ID: <20230129025747.682282-9-pizhenwei@bytedance.com> (raw)
In-Reply-To: <20230129025747.682282-1-pizhenwei@bytedance.com>

Move queue_index, CryptoDevCompletionFunc and opaque into struct
CryptoDevBackendOpInfo, then cryptodev_backend_crypto_operation()
needs an argument CryptoDevBackendOpInfo *op_info only. And remove
VirtIOCryptoReq from cryptodev. It's also possible to hide
VirtIOCryptoReq into virtio-crypto.c in the next step. (In theory,
VirtIOCryptoReq is a private structure used by virtio-crypto only)
