[Qemu-block] [PATCH 2/3] block: use bdrv_get_device_or_node_name() in error messages |
Date: |
Wed, 8 Apr 2015 12:29:19 +0300 |
There are several error messages that identify a BlockDriverState by
its device name. However those errors can be produced in nodes that
don't have a device name associated.
In those cases we should use bdrv_get_device_or_node_name() to fall
back to the node name and produce a more meaningful message. The
messages are also updated to use the more generic term 'node' instead
of 'device'.
