Subject: [PATCH v10 00/34] Add subcluster allocation to qcow2
Date: Fri, 3 Jul 2020 17:57:46 +0200 [thread overview]
Message-ID: <cover.1593791819.git.berto@igalia.com> (raw)
Based-on: <20200610094600.4029-1-berto@igalia.com>
Hi,
here's the new version of the patches to add subcluster allocation
support to qcow2.
Please refer to the cover letter of the first version for a full
description of the patches:
https://lists.gnu.org/archive/html/qemu-block/2019-10/msg00983.html
There are no major changes compared to v9, just fixes for the problems
discovered by Max (see below for details).
If you want to test this series make sure to apply this patch first:
https://lists.gnu.org/archive/html/qemu-block/2020-06/msg00504.html

v10:
- Patch 02: Set host_offset to 0 also when the L2 table is empty [Max]
- Patch 21: Fix assertion (l2_size -> l2_slice_size) and compiler
warnings [Max]
- Patch 28: Let qcow2_co_truncate() make subcluster-aligned calls to
qcow2_cluster_zeroize() [Max]
Assert that offset is aligned in zero_in_l2_slice() [Max]
- Patch 31: Use -ENOTSUP instead of -EINVAL [Max]
- Patch 34: Remove length modifiers from printf [Max]
Forbid running the test with refcount_bits=1 [Max]
