find_next_set_bit() is just badly implemented. There is no need to
redesign the data structure. It should be a simple matter of:

[PATCH v19 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:
