Jason Xing says: ==================== tcp: add two missing addresses when using trace When I reviewed other people's patch [1], I noticed that similar things also happen in tcp_event_skb class and tcp_event_sk_skb class. They don't print those two addrs of skb/sk which already exist. In this patch, I just do as other trace functions do, like trace_net_dev_start_xmit(), to know the exact flow or skb we would like to know in case some systems doesn't support BPF programs well or we have to use /sys/kernel/debug/tracing only for some reasons.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
