...n 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) cmdq: a new virtqueue to send commands between the device and driver. Currently, it supports commands to report memory stats (replace the old statq mechanism) and report guest unused pages. Change Log: v11->v12: 1) xbitmap: use the xbitmap from Matthew Wilcox to record ballooned pages. 2) virtio-ring: enable the driver to build up a desc chain using vring desc. 3) virtio-ring: Add locking to the existing START_USE() and END_USE() macro to...
