[Qemu-devel] [PATCH v3 20/32] blockdev: Separate dmg probe from its driver |
Date: |
Tue, 5 Jul 2016 11:24:20 -0400 |
Completes the separation of the dmg probe from the dmg driver. The dmg
probe now returns the format in addition to the score, allowing
correlation of the score and driver without the probe function being
part of the driver itself.
