Hi Kevin and Stefan,
As the realize of bdrv_discard, and this patch has been received, but
I have some question.
This adds a bdrv_discard function to qcow2 that frees the discarded clusters.
It does not yet pass the discard on to the underlying file system driver, but
the space can be reused

It does not yet pass the discard on to the underlying file system driver, but
the space can be reused by future writes to the image.
