Patrick, while looking for other usage of p2m_mem_paging_populate(), I found two calls in __gnttab_copy(). They set the error gnttab_copy_t->status to -ENOENT. Should this better be something from the GNTST_* namespace? I did not see a check for -ENOENT "on the other side". At least the kernel drivers in SLES11 do only check for GNTST_okay and GNTST_eagain and GNTST_bad_page. And a quick search for op->status usage shows a mix of GNTST_* and status != 0. While it may not make much difference, perhaps there should be some translation between the granttable error namespace and other namespaces.
