From 6f8f015c0cd9f3ea44de4d73144db98beef97e3c Mon Sep 17 00:00:00 2001 From: Alberto Garcia Date: Thu, 11 Oct 2018 13:58:02 +0300 Subject: qcow2: Get the request alignment for encrypted images from QCryptoBlock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This doesn't have any practical effect at the moment because the values of BDRV_SECTOR_SIZE, QCRYPTO_BLOCK_LUKS_SECTOR_SIZE and QCRYPTO_BLOCK_QCOW_SECTOR_SIZE are all the same (512 bytes), but future encryption methods could have different requirements.
