[PATCH 00/12] Preparatory patches for live migration downtime improvement

[Si-Wei Liu <si-wei.liu@oracle.com>]

This small series is a spin-off from [1], where the patches
already acked from that large patchset may get merged earlier
without having to wait for those that are still in review.

The last 3 patches (10 - 12) are bug fix to an issue where
cancellation of ongoing migration may lead to busted network.
These are the only outstanding patches in this patchset with
no acknowledgement received as yet. Please try to review
them at the earliest oppotunity. Thanks!

Regards,
-Siwei
