Subject: [PATCH v12 0/3] qcow2: advanced compression options
Date: Mon, 2 Dec 2019 15:15:03 +0300 [thread overview]
Message-ID: <1575288906-551879-1-git-send-email-andrey.shinkevich@virtuozzo.com> (raw)
The compression filter driver is introduced as suggested by Max.
A sample usage of the filter can be found in the test #214.
Now, multiple clusters can be written compressed.
It is useful for the backup job.
v12:
01: Missed to change the driver interface .bdrv_co_block_status
from _status_from_backing to _status_from_file (noticed by
Vladimir).
Andrey Shinkevich (3):
block: introduce compress filter driver
qcow2: Allow writing compressed data of multiple clusters
tests/qemu-iotests: add case to write compressed data of multiple
clusters
