When forgetting to unmap a grant page and quitting the tool 2). when unmapping appropriately. Attached are the logs from the domain exporting the grants (domain 4), and the faulting (domain 3 and domain 5). This is using this patchset (devel/gntalloc.v6) and sticking it on top of 2.6.38-rc2 with a whole bunch of patches.
