[PATCH v2 0/4] qcow2: Misc BDRV_SECTOR_SIZE updates

From: Alberto Garcia
Subject: [PATCH v2 0/4] qcow2: Misc BDRV_SECTOR_SIZE updates
Date: Thu, 9 Jan 2020 20:12:58 +0100

This small series gets rid of all the remaining instances of hardcoded
sector sizes in the qcow2 code and adds a check for images whose
virtual size is not a multiple of the sector size.

See the individual patches for details.


- Modify output of iotest 080 to make it easier to understand [Nir]
- Use the QEMU_IS_ALIGNED() macro instead of the modulus operator [Nir]
- Tighten some assertions [Kevin]

v1: https://lists.gnu.org/archive/html/qemu-block/2020-01/msg00139.html

Alberto Garcia (4):
  qcow2: Require that the virtual size is a multiple of the sector size
  qcow2: Don't round the L1 table allocation up to the sector size
  qcow2: Tighten cluster_offset alignment assertions
  qcow2: Use BDRV_SECTOR_SIZE instead of the hardcoded value
