help
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.
