$ grep EIO drivers/xen/privcmd/*

nothing

$ grep EINVAL drivers/xen/privcmd/*
drivers/xen/privcmd/privcmd.c:		rc = -EINVAL;
drivers/xen/privcmd/privcmd.c:			rc = -EINVAL;
drivers/xen/privcmd/privcmd.c:			return -EINVAL;
drivers/xen/privcmd/privcmd.c:			return -EINVAL;
drivers/xen/privcmd/privcmd.c:		ret = -EINVAL;

So not a privcmd issue.

I'm just going to close this as not-a-bug, because I don't want to try and figure out where it should go. It's clear the reporter needs to double check the test to know what is returning what before reopening it anyway.
