It might be useful to compress images during block-stream;
this way the user can merge compressed images of a backing chain and
the result will remain compressed.
Anton Nefedov (4):
qcow2: reject unaligned offsets in write compressed
block: support compressed write for copy-on-read
block-stream: add compress option
iotest 030: add compressed block-stream test
Pavel Butsykin (1):
qcow2: multiple clusters write compressed
