[Qemu-devel] [PATCH 3/5] crypto/block: rename qcrypto_block_*crypt_helpe


From: Vladimir Sementsov-Ogievskiy
Subject: [Qemu-devel] [PATCH 3/5] crypto/block: rename qcrypto_block_*crypt_helper
Date: Tue, 4 Dec 2018 21:46:55 +0300

Rename qcrypto_block_*crypt_helper to qcrypto_cipher_*crypt_helper, as
it's not about QCryptoBlock. This is needed to introduce
qcrypto_block_*crypt_helper in the next commit, which will have
QCryptoBlock pointer and than will be able to use additional fields of
it, which in turn will be used to implement thread-safe QCryptoBlock
operations.
