[Qemu-devel] [PATCH v5 0/6] block/qcow2: Image file option amendment |

This series adds support to qemu-img, block and qcow2 for amending image
options on existing image files.
Depends on:
- option: Add assigned flag to QEMUOptionParameter
- qcow2-refcount: Snapshot update for zero clusters (series, v3)
- Add metadata overlap checks (series, v5)
v5:
- added a new function for emptying a cache (patch 2)
- fixed rounding for the bitmap size in qcow2_expand_zero_clusters
- now empties the cache in qcow2_expand_zero_clusters instead of simply
flushing it
- factored out assignment check in qcow2_amend_options
- fixed resizing by moving it to the end of qcow2_amend_options
- fixed expected test result for resizing in addition to a version
upgrade
v4:
- rebased on the metadata overlap check series (and fit to it)
- split patch 2 into three distinct patches (2, 3 and 4)
- extended test for zero expansion on backed and inactive backed clusters
(and fixed according to the metadata overlap check series (i.e.,
adjusted header length))
- fixed zero expansion with shared L2 tables
v3:
- deallocate non-preallocated zero clusters on non-backed images instead
of zero expanding them
- qcow2 version downgrade: error out on refcount_order != 4
- implemented Eric's comments regarding the qemu-img amend and img_amend
itself
v2:
- Generally implemented Kevin's comments, especially:
- Zero cluster expansion for inactive L2 tables
- Correct handling of preallocated zero clusters
- More test cases
Max Reitz (6):
block: Image file option amendment
qcow2-cache: Empty cache
qcow2-cluster: Expand zero clusters
qcow2: Save refcount order in BDRVQcowState
qcow2: Implement bdrv_amend_options
qemu-iotest: qcow2 image option amendment
