Mark the function virtballoon_migratepage() as static in
virtio_balloon.c because it is not used outside this file.
This eliminates the following warning in virtio_balloon.c:
drivers/virtio/virtio_balloon.c:372:5: warning: no previous prototype for
‘virtballoon_migratepage’ [-Wmissing-prototypes]
The virtio-net driver currently uses netdev_alloc_frag() for GFP_ATOMIC

per-receive queue page frags for GFP_ATOMIC allocation. This change unifies

successively smaller page allocs (down to ord

From: Asias He
vqs are freed in virtscsi_freeze but the hotcpu_notifier is not
unregistered. We will have a use-after-free usage when the notifier
callback is called after virtscsi_freeze.
