From: David Stevens <stevensd@xxxxxxxxxxxx> 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/20240318091034.535573-1-stevensd@xxxxxxxxxx/ 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 drivers/virtio/virtio_balloon.c | 84 +++++++++++++++++++++------------ 1 file changed, 55 insertions(+), 29 deletions(-) base-commit: e8f897f4afef0031fe618a8e94127a0934896aba -- 2.44.0.291.gc1ea87d7ee-goog
