Yonghong Song 9f2f5d7830 libbpf: Improve BPF_PROG2 macro code quality and description Commit `34586d29f8` ("libbpf: Add new BPF_PROG2 macro") added BPF_PROG2 macro for trampoline based programs with struct arguments. Andrii made a few suggestions to improve code quality and description. This patch implemented these suggestions including better internal macro name, consistent usage pattern for __builtin_choose_expr(), simpler macro definition for always-inline func arguments and better macro description.

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.
