Ah, my bad, sorry about that. I see that they are different now.
One is v1 the other v2, both targeting tcp tracing... Easy to miss

Not only do you post it before we "officially" open net-next but

In addition to knowing the 4-tuple of the flow which generates RST,
the reason why it does so is very important because we have some
cases where the RST should be sent and have no clue which one
exactly.
Adding location of reset process can help us more, like what

Introducing entry_saddr and entry_daddr parameters in this macro
for later use can help us record the reverse 4-tuple by analyzing
the 4-tuple of the incoming skb when receiving.

Put the macro into another standalone file for better extension.
Some tracepoints can use this common part in the future.

Prior to this patch, what we can see by enabling trace_tcp_send is
only happening under two circumstances:
1) active rst mode
2) non-active rst mode and based on the full socket
That means the inconsistency occurs if we use tcpdump and trace
simultaneously to see how rst

Before this, we miss some cases where the TCP layer could send rst but
we cannot trace it. So I decided to complete it :)
