...1) PAGE_CHUNK_TYPE_BALLOON: Ballooned (i.e. inflated/deflated) pages to chunk. For the ballooned type, it uses the basic chunk msg format: virtio_balloon_page_chunk_hdr + virtio_balloon_page_chunk * MAX_PAGE_CHUNKS 2) PAGE_CHUNK_TYPE_UNUSED: unused pages to chunk. It uses this miscq msg format: miscq_hdr + virtio_balloon_page_chunk_hdr + virtio_balloon_page_chunk * MAX_PAGE_CHUNKS The chunk msg is actually the payload of the miscq msg. >> +#define MAX_PAGE_CHUNKS 4096 > This is an order-4 allocation.
