[Qemu-block] [PATCH v3 26/32] blockdev: Separate vdi probe from its driver |
Date: |
Tue, 5 Jul 2016 11:24:26 -0400 |
Completes the separation of the vdi probe from the vdi driver. The
vdi 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.
