The bpf programs that this patch changes require the BPF_PROG macro. The BPF_PROG macro is defined in the libbpf's bpf_tracing.h. Some tests include bpf_tcp_helpers.h which includes bpf_tracing.h. They don't need other things from bpf_tcp_helpers.h other than bpf_tracing.h. This patch simplifies it by directly including the bpf_tracing.h. The motivation of this unnecessary code churn is to retire the bpf_tcp_helpers.h by directly using vmlinux.h. Right now, the main usage of the bpf_tcp_helpers.h is the partial kernel socket definitions (e.g. socket, sock, tcp_sock). While the test cases continue to grow, fields are kept adding to those partial socket definitions (e.g. the recent bpf_cc_cubic.c test which tried to extend bpf_tcp_helpers.c but eventually used the vmlinux.h instead). The idea is to retire bpf_tcp_helpers.c and consistently use vmlinux.h for the tests that require the kernel sockets. This patch tackles the obvious tests that can directly use bpf_tracing.h instead of bpf_tcp_helpers.h.

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 reStructuredText 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.
