Good question.
Unfortunately it doesn't reduce what our patch set needs to do at this
point. The primary namespace changes that happened about 10+ kernel
versions ago (circa 2.6.28) are essential for containers and reliable
checkpoint/restart. Since then namespace improvements have nothing or very
little to do with enabling checkpoint/restart -- it's all for containers.
