v9:
* 01: fix error checking and reporting in qcow2_amend compression type part
[Vladimir]
* 03: replace asserts with -EIO in qcow2_zstd_decompression [Vladimir,
Alberto]
* 03: reword/amend/add comments, fix typos [Vladimir]
v8:
* 03: switch zstd API from simple to stream [Eric]
No need to state a special cluster layout for zstd
compressed clusters.
v7:
* use qapi_enum_parse instead of the open-coding [Eric]
* fix wording, typos and spelling [Eric]
v6:
* "block/qcow2-threads: fix qcow2_decompress" is removed from the series
since it has been accepted by Max already
* add compile time checking for Qcow2Header to be a multiple of 8 [Max,
Alberto]
* report error on qcow2 amending when the compression type is actually
chnged [Max]
* remove the extra space and the extra new line [Max]
* re-arrange acks and signed-off-s [Vladimir]
v5:
* replace -ENOTSUP with abort in qcow2_co_decompress [Vladimir]
* set cluster size for all test cases in the beginning of the 287 test
v4:
* the series is rebased on top of 01 "block/qcow2-threads: fix
qcow2_decompress"
* 01 is just a no-change resend to avoid extra dependencies. Still, it may
be merged in separate
v3:
* remove redundant max compression type value check [Vladimir, Eric]
(the switch below checks everything)
* prevent compression type changing on "qemu-img amend" [Vladimir]
* remove zstd config setting, since it has been added already by
"migration" patches [Vladimir]
* change the compression type error message [Vladimir]
* fix alignment and 80-chars exceeding [Vladimir]
v2:
* rework compression type setting [Vladimir]
* squash iotest changes to the compression type introduction patch
[Vladimir, Eric]
* fix zstd availability checking in zstd iotest [Vladimir]
* remove unnecessry casting [Eric]
* remove rudundant checks [Eric]
* fix compressed cluster layout in qcow2 spec [Vladimir]
* fix wording [Eric, Vladimir]
* fix compression type filtering in iotests [Eric]
v1:
the initial series
Denis Plotnikov (4):
qcow2: introduce compression type feature
qcow2: rework the cluster compression routine
qcow2: add zstd cluster compression
iotests: 287: add qcow2 compression type test
