This patch provides the value of the currently outstanding pages claimed for a specific domain. This is a value that influences the global outstanding claims value (See patch: "xl: 'xl info' print outstanding claims if enabled") returned via xc_domain_get_outstanding_pages hypercall. This domain value decrements as the memory is populated for the guest and eventually reaches zero. With this patch it is possible to utilize this field.
