blockdev: mirror: do not require a root block node

[PATCH 0/3] blockdev: mirror: do not require a root block node

Posted by Fiona Ebner 1 month, 2 weeks ago

The mirror block job currently only operates on a root block node. It
might be desired to use a throttle node as the root node for limiting
the guest IO, without also limiting mirror operations.

There is no obvious reason why mirror should only be able to operate
on a root block node.
