All three of these patches came from these discussions:
http://marc.info/?t=129552800100005&r=1&w=2
http://marc.info/?t=129646395700004&r=1&w=2
http://marc.info/?t=129708178200007&r=1&w=2

1/3 was changed just because it seemed to be the way the interface was
used

2/3 was changed because the 2.6.38 kernel fails to load certain selinux
policies which worked under 2.6.37 because of this lack of functionality

3/3 was changed just because that's how maybe it should work, although
there are no known users.

I can certainly update 2/3 to better explain the rational but I can't
really do any better on 1/3 and 3/3 other than to just say what the
change is......
