Comment 1 Andrew Jones 2011-07-07 07:06:06 UTC

$ 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.

Seems this bug was solved by bug 717068.
