From 0270417c87d330243eb713a3312ea5e39e192994 Mon Sep 17 00:00:00 2001 From: Vladimir Sementsov-Ogievskiy Date: Fri, 7 Dec 2018 19:13:49 +0300 Subject: crypto/block: rename qcrypto_block_*crypt_helper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rename qcrypto_block_*crypt_helper to qcrypto_block_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.
