From: Qiang Liu <redacted> Balloon inflate/deflate block in tell_host() for host buffer consumption. Host-side stalls are easily mistaken for guest allocation issues. Add virtio_balloon_host_ack to record tell_host() wait time, virtqueue and PFN count, to split balloon latency between guest and host. Signed-off-by: Qiang Liu <redacted>
