Host mappings via grant tables are refcounted via the mapping PTEs, not directly via the maptrack table. So if we destroy pagetables first, we can drop all refcounts before we call the gnttab_release_mappings(), and the maptrack can have dangling domain id's at that point. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
