[PATCH v2 0/2] qcow2: don't leave partially initialized file on image creation

Posted by Maxim Levitsky 3 years, 6 months ago

Use the bdrv_co_delete_file interface to delete the underlying
file if qcow2 initilization fails (e.g due to bad encryption secret)

This gives the qcow2 the same treatment as to luks.

V2: added a patch to fix a memory leak.
