[Qemu-devel] [PATCH 00/19] qcow2: Add basic version 3 support

[Kevin Wolf]

In this submission, the TODO items that the RFC still had should all be cleaned
up now. The parts of the spec and the code that refer to not yet implemented
features are moved to two RFC patches at the end of the series, which are not
meant to be applied at this point. I think the rest can be merged very soon.

Kevin Wolf (18):
  Specification for qcow2 version 3
  qcow2: Save disk size in snapshot header
  qcow2: Ignore reserved bits in get_cluster_offset
  qcow2: Ignore reserved bits in count_contiguous_clusters()
  qcow2: Fail write_compressed when overwriting data
  qcow2: Ignore reserved bits in L1/L2 entries
  qcow2: Refactor qcow2_free_any_clusters
  qcow2: Simplify count_cow_clusters
  qcow2: Ignore reserved bits in refcount table entries

  [RFC] Possible qcow2 specification extensions
