Introduce interfaces for ballooning enqueueing and dequeueing of a list of pages. These interfaces reduce the overhead of storing and restoring IRQs by batching the operations. In addition they do not panic if the list of pages is empty. Cc: "Michael S. Tsirkin" <mst at redhat.com> Cc: Jason Wang <jasowang at redhat.com> Cc: linux-mm at kvack.org Cc: virtualization at

Introduce interfaces for ballooning enqueueing and dequeueing of a list of pages. These interfaces reduce the overhead of storing and restoring IRQs by batching the operations. In addition they do not panic if the list of pages is empty. Cc: Jason Wang <jasowang at redhat.com> Cc: linux-mm at kvack.org Cc: virtualization at lists.linux-foundation.org Acked-by: Michael S.

From: Wei Wang <wei.w.wang at intel.com> A #GP is reported in the guest when requesting balloon inflation via virtio-balloon. The reason is that the virtio-balloon driver has removed the page from its internal page list (via balloon_page_pop), but balloon_page_enqueue_one also calls "list_del" to do the removal. This is necessary when it's used from balloon_page_enqueue_list,

Patches 1-2: Support for compaction Patch 3: Support for memory shrinker - disabled by default Patch 4: Split refused pages to improve performance v3->v4: * "get around to" comment [Michael] * Put list_add under page lock
