skb allocation / cosumption tracer - Add consumption tracepoint This patch adds a tracepoint to skb_copy_datagram_iovec, which is called each time a userspace process copies a frame from a socket receive queue to a user space buffer. It allows us to hook in and examine each sk_buff that the system receives on a per-socket bases, and can be use to compile a list of which skb's were received by which processes.
