[Qemu-devel] [PATCH v4 0/7] block/qcow2: Improve zero cluster expansion |

The main purpose of this series is to add a progress report to
qemu-img amend. This is achieved by adding a callback function to
bdrv_amend_options() - the reasons for this choice are explained in
patch 1.
While adapting qcow2's expand_zero_clusters_in_l1() accordingly, I
noticed a way to simplify it and get rid of the rather ugly bitmap used
there (patch 6).
Changes from v3 (v4 is a rebase of v3 on current master)
- Patch 2: There is BlockBackend now (only contextual)
- Patch 4: An instance of g_try_malloc0() instead of g_malloc0() (only
contextual)
- Patch 5: Changes in the qcow2 check functions due to my "qcow2: Fix
image repairing" series (only contextual)
- Patch 6: Originally, contained a hunk which removed a g_malloc0() and
the buffer size calculation before it; now, it's a g_try_malloc0() and
therefore the hunk has to remove the error handling as well. This is a
functional change, but I decided to keep the R-bs anyway because it is
really straightforward.
Since with the exception of patch 6 all of these were contextual changes
(and the change to patch 6 was really straightforward), I kept all the
Reviewed-bys and this series is therefore still fully reviewed.
git-backport-diff against v3:
Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
