From: David Stevens <[email protected]>
The virtio_balloon driver uses wakeup sources to allow the guest to
enter system power management sleep states (e.g. s2idle) without running
the risk of becoming unresponsive to cooperative memory management
requests from the host. This series fixes an issue where wakeup sources
for inflate/deflate were improperly shared between drivers. It also
closes a race where stats requests that come in immediately before a
sleep state transition could fail to be handled in a timely manner.
v1: https://lore.kernel.org/lkml/[email protected]/
v1 -> v2:
- Add comment about virtio-balloon's wakeup source
- Rename virtio-balloon wakeup event macros
David Stevens (2):
virtio_balloon: Give the balloon its own wakeup source
virtio_balloon: Treat stats requests as wakeup events
