[PATCH v25 0/2] Virtio-balloon: support free page reporting
...ey are
used and written.
ChangeLog:
v24->v25:
- mm: change walk_free_mem_block to return 0 (instead of true) on
completing the report, and return a non-zero value from the
callabck, which stops the reporting.
- virtio-balloon:
- use enum instead of define for VIRTIO_BALLOON_VQ_INFLATE etc.
- avoid __virtio_clear_bit when bailing out;
- a new method to avoid reporting the some cmd id to host twice
- destroy_workqueue can cancel free page work when the feature is
negotiated;
- fail probe when the free page vq size is less than 2.
