[PATCH v20 6/7] virtio-balloon: VIRTIO_BALLOON_F_FREE_PAGE_VQ

Negotiation of the VIRTIO_BALLOON_F_FREE_PAGE_VQ feature indicates the support of reporting hints of guest free pages to host via virtio-balloon. Host requests the guest to report free pages by sending a new cmd id to the guest via the free_page_report_cmd_id configuration register. When the

[PATCH v20 2/7] xbitmap: potential improvement

This patch made some changes to the original xbitmap implementation from the linux-dax tree: - xb_set_bit: delete the new inserted radix_tree_node when failing to get the per cpu ida bitmap, this avoids the kind of memory leak of the unused radix tree node left in the tree. - xb_preload:

[PATCH v20 4/7] virtio-balloon: VIRTIO_BALLOON_F_SG

Add a new feature, VIRTIO_BALLOON_F_SG, which enables the transfer of balloon (i.e. inflated/deflated) pages using scatter-gather lists to the host. The implementation of the previous virtio-balloon is not very efficient, because the balloon pages are transferred to the host by one array each

This patch series enhances the existing virtio-balloon with the following new features: 1) fast ballooning: transfer ballooned pages between the guest and host in chunks using sgs, instead of one array each time; and 2) free page block reporting: a new virtqueue to report guest free pages to the

[PATCH v20 5/7] mm: support reporting free page blocks
