	   This tracer helps developers/sysadmins correlate skb allocation and

	   consumption.  The idea being that some processes will primarily consume data

	   that was allocated on certain numa nodes.  By being able to visualize which

	   nodes the data was allocated on, a sysadmin or developer can optimize the

	   scheduling of those processes to cut back on cross node chatter.
