This situation signals that the mapping domain cleared the granted mapping by simply zapping the PTE, rather than going thru the explicit grant-unmap operation. The effect of this is undefined (although of course it should not crash Xen!) and for sanity's sake I prefer to crash the offender whenever I can detect that this has happened. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
