Thanks for the patch! Would be nice to actually test the code path which caused the initial addition of VM_IO. I think I lack the hardware to excersise them. In my 4.4 based sources I get the following unresolved symbols. If that happens to work in mainline the failures should at least be considered during backporting of this proposed patch to the stable trees. ERROR: "__mpol_dup" [drivers/xen/xen-gntdev.ko] undefined! ERROR: "get_task_policy" [drivers/xen/xen-gntdev.ko] undefined! Appearently these symbols lack just an EXPORT_SYMBOL_GPL. Olaf
