[Qemu-devel] [RFC 0/2] virtio-balloon: Some further fixes

Posted by David Gibson 6 years, 8 months ago

Commits f6deb6d..ee1cd00 made some reworks to the balloon device to
fix behaviour on systems (both host and guest) which don't have 4kiB
pages.  However it introduced a couple of problems, which this series
addresses.

David Gibson (2):
  virtio-balloon: Fix possible guest memory corruption with inflates &
    deflates
  virtio-balloon: Restore MADV_WILLNEED hint on balloon deflate
