[PATCH v11 0/6] Virtio-balloon Enhancement

[Wei Wang <wei.w.wang@intel.com>]

This patch series enhances the existing virtio-balloon with the following new
features:
1) fast ballooning: transfer ballooned pages between the guest and host in
chunks, instead of one by one; and
2) cmdq: a new virtqueue to send commands between the device and driver.
Currently, it supports commands to report memory stats (replace the old statq
mechanism) and report guest unused pages.

Liang Li (1):
  virtio-balloon: deflate via a page list

Wei Wang (5):
  virtio-balloon: coding format cleanup
  virtio-balloon: VIRTIO_BALLOON_F_PAGE_CHUNKS
  mm: function to offer a page block on the free list
  mm: export symbol of next_zone and first_online_pgdat
  virtio-balloon: VIRTIO_BALLOON_F_CMD_VQ
