[PATCH v8 0/3] qcow2: add zstd cluster compression

[Vladimir Sementsov-Ogievskiy]

Hi all!

Here is my proposal, about how to correctly update qcow2 specification
to introduce new field, keeping in mind currently existing images and
downstream Qemu instances.

v8: Add padding, and clarify "zero equals absence" concept.
    Move some points to commit message from the spec itself.
    Fix s/108/105 in 02

Vladimij Sementsov-Ogievskiy (3):
  docs: improve qcow2 spec about extending image header
  docs: define padding for qcow2 header
  docs: qcow2: introduce compression type feature
