Hi, v2 cover letter: https://lists.nongnu.org/archive/html/qemu-block/2022-03/msg01260.html
v1 cover letter: https://lists.nongnu.org/archive/html/qemu-block/2021-03/msg00651.html This series fixes the qcow2 refcount structure rebuilding mechanism for when the qcow2 image file doesn’t allow writes beyond the end of file (e.g. because it’s on an LVM block device). v3: - Added patch 3 (didn’t squash this into patch 1, because (a) Eric gave his R-b on 1 as-is, and (b) I ended up retouching rebuild_refcount_structure() as a whole, not just the new helper, so a dedicated patch made more sense) - In patch 1: Changed `assert(reftable_size_changed == true)` to just `assert(reftable_size_changed)` - In patch 2: In comments, replaced “were” by “was” 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 001/3:[0002] [FC] 'qcow2: Improve refcount structure rebuilding' 002/3:[0006] [FC] 'iotests/108: Test new refcount rebuild algorithm' 003/3:[down] 'qcow2: Add errp to rebuild_refcount_structure()' Hanna Reitz (3): qcow2: Improve refcount structure rebuilding iotests/108: Test new refcount rebuild algorithm qcow2: Add errp to rebuild_refcount_structure() block/qcow2-refcount.c | 353 ++++++++++++++++++++++++++----------- tests/qemu-iotests/108 | 259 ++++++++++++++++++++++++++- tests/qemu-iotests/108.out | 81 +++++++++ 3 files changed, 587 insertions(+), 106 deletions(-) -- 2.35.1
