Re: [Qemu-devel] Virtio 9p live migration patches

[Benoît Canet]

There is still the need to serialize the fid linked list.
I saw in the current code base that virtio-blk.c was using the old API to
serialize a linked list.

Does writing support for serializing linked list in vmstate worth it ?
Or is it better to keep the old API to serialize ?
