[Qemu-devel] [PATCH 9/9] pci: mark device having guest unplug request pending

[Jens Freimann]

Set pending_deleted_event before triggering the unplug request and reset
it in the unplug handler when the device is marked as partially
hotplugged. This is required to be able to plug it back in in case of a
migration failure.
