[PATCH v20 3/7 RESEND] xbitmap: add more operations
This patch adds support to find next 1 or 0 bit in a xbmitmap range and clear a range of bits. More possible optimizations to add in the future: 1) xb_set_bit_range: set a range of bits. 2) when searching a bit, if the bit is not found in the slot, move on to the next slot directly. 3) add tags to help searching.

[PATCH v20 0/7] 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 array each time; and 2) free page block reporting: a new virtqueue to report guest free pages to the host. The second feature can be used to accelerate live migration of VMs. Here are some details: Live

[PATCH v21 1/5] xbitmap: Introduce xbitmap
From: Matthew Wilcox <mawilcox at microsoft.com> 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.

[PATCH v20 3/7 RESEND] xbitmap: add more operations
OK, here's a rewrite of xbitmap. Compared to the version you sent: - xb_find_set() is the rewrite I sent out yesterday. - xb_find_clear() is a new implementation. I use the IDR_FREE tag to find clear bits. This led to me finding a bug in radix_tree_for_each_tagged(). - xb_zero() is also a new implementation (replacing xb_clear_bit_range). It should also be more efficient in deep
