From 0af09eebf475d1511fae90aa30a920cd1f29302b Mon Sep 17 00:00:00 2001 From: Dan Magenheimer Date: Mon, 25 Feb 2013 15:10:08 -0500 Subject: xc: export outstanding_pages value in xc_dominfo structure. 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. This patch is neccessary for "xl: export 'outstanding_pages' value from xcinfo" patch.
