If this were in -rc or we are only a couple releases out, sure, moving
that to the end would be the right thing to do but that's not the case
and it bothers me that the patch essentially trades in about the same
magnitude of unknown risk.  No matter which way you spin it, unknown
risk of similar magnitude is not better than known risk and it's
pretty certain that we'll have all three variants out in the wild for
the foreseeable future.

If this has to happen, it should be moving Ngid right after TracerPid
not at the end of file.

Thanks.
