Mark Johnston 494fe2e050 gntdev: Handle errors from suword32() in gntdev_alloc_gref() ... Try to copy out output values before handling errors, and check that we did so successfully. In particular, it doesn't seem sensible to ignore errors here, otherwise userspace won't have any way to refer to the allocations. This is in preparation for annotating copyin() and related functions with __result_use_check.
