+          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.
