[PATCH v8 0/3] qcow2: advanced compression options
Posted by Andrey Shinkevich 4 years, 4 months ago
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.

v8: The filter child was changed from the 'backing' to the 'file' one.

  Discussed in the email thread with the message ID
