The next patch will introduce a new "struct bpf_tcp_sock" which exposes the same tcp_sock's fields already exposed in "struct bpf_sock_ops". This patch refactor the existing convert_ctx_access() codes for "struct bpf_sock_ops" to get them ready to be reused for "struct bpf_tcp_sock". The "rtt_min" is not refactored in this patch because its handling is different from other fields. The SOCK_OPS_GET_TCP_SOCK_FIELD is new. All other SOCK_OPS_XXX_FIELD changes are code move only.

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.
