[Qemu-devel] [PATCH v3 0/7] block/qcow2: Improve zero cluster expansion

[Max Reitz <mreitz@redhat.com>]

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).

This series depends on v2 of my "qemu-img: Allow source cache mode
specification" series.


Changes from v2:
 - Patch 1: Fixed misspelling in the commit message [Eric]


git-backport-diff against v2:

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
