The recent support for inline annotations in control flow graphs generated by bpftool introduced the usage of the "__fallthrough" macro in a switch/case block in btf_dumper.c. This change went through the bpf-next tree, but resulted in a merge conflict in linux-next, because this macro has been renamed "fallthrough" (no underscores) in the meantime. To address the conflict, we temporarily switch to a simple comment instead of a macro.

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.
