Dave. Another and probably better way of looking at this is we need
essentially the same code in sysfs however we implement it. The only
practical difference is do we get the namespaces from the mount of
sysfs or from the current process doing the reading.
If you would like to take this in the direction of looking at the
mount point for the information and seeing if there are optimizations
we can apply with static information free.
Wherever we end up I think this code is a fairly decent starting place.
