The refcnt is dropped whenxenheap_pages field reduces to zero in common/page_alloc.c:free_domheap_pages(). Hmm.. but the console page is a "domain page", no?After looking at more code I convinced myself that a page not owned by the domain but owned by another is "foreign". -JX _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
