[Qemu-devel] [PATCH 04/11] qdev: add to BusState "hotplug-handler" link |
Date: |

It will allow to reuse field with different BUSes, reducing code duplication.
Field is intended fot replacing 'hotplug_qdev' field in PCIBus and also
will allow to avoid adding equivalent field to DimmBus with possiblitity
to refactor other BUSes to use it instead of custom field.
In addition once all users of allow_hotplug field are converted to new
API, link could replace allow_hotplug in qdev hotplug code.
