Subject: [PATCH v6 0/3] qcow2: advanced compression options
Date: Mon, 11 Nov 2019 19:04:34 +0300 [thread overview]
Message-ID: <1573488277-794975-1-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.
v6: The new approach to write compressed data was applied. The patch
v5 4/4 with the block-stream compress test case was removed from
the series.
Discussed in the email thread with the message ID
