+ 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.
