[Qemu-devel] [PULL 06/29] iotests: Make BD-{remove, insert}-medium use @id

Kevin Wolf posted 29 patches 7 years, 2 months ago
There is a newer version of this series
[Qemu-devel] [PULL 06/29] iotests: Make BD-{remove, insert}-medium use @id
Posted by Kevin Wolf 7 years, 2 months ago 
From: Max Reitz <mreitz@redhat.com>

In some cases, these commands still use the deprecated @device
parameter.  Fix that so we can later drop that parameter from their
interface.
