[PATCH v15 5/5] virtio-balloon: VIRTIO_BALLOON_F_CTRL_VQ

Add a new vq, ctrl_vq, to handle commands between the host and guest. With this feature, we will be able to have the control plane and data plane separated. In other words, the control related data of each feature will be sent via the ctrl_vq cmds, meanwhile each feature may have its own data

[PATCH v15 4/5] mm: support reporting free page blocks

This patch adds support to walk through the free page blocks in the system and report them via a callback function. Some page blocks may leave the free list after zone->lock is released, so it is the caller's responsibility to either detect or prevent the use of such pages. One use example of

[PATCH v15 3/5] 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 one by one. Here is

[PATCH v15 2/5] lib/xbitmap: add xb_find_next_bit() and xb_zero()

xb_find_next_bit() is used to find the next "1" or "0" bit in the given range. xb_zero() is used to zero the given range of bits. Signed-off-by: Wei Wang Cc: Andrew Morton Cc: Matthew Wilcox Cc: Michal Hocko

[PATCH v15 1/5] lib/xbitmap: Introduce xbitmap

From: Matthew Wilcox The eXtensible Bitmap is a sparse bitmap representation which is efficient for set bits which tend to cluster. It supports up to 'unsigned long' worth of bits, and this commit adds the bare bones -- xb_set_bit(), xb_clear_bit() and xb_test_bit().

[PATCH v15 0/5] Virtio-balloon Enhancement

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 by one; and 2) free page block reporting: a new virtqueue to report guest free pages to the host. The
