From: "Maciej S.

However, device state packets aren't compatible with zerocopy - the data buffer isn't getting kept pinned until multifd channel flush. Make sure to mask that QIO_CHANNEL_WRITE_FLAG_ZERO_COPY flag in a multifd send thread if the data being sent is device state.

Is this qemu-stable material (for 10.0)? I'm picking it up for 10.0 branch, please let me know if I shouldn't. Thanks, /mjt
