mainlining shenanigans
9165e1d70f
The bpftool sources include code to walk file trees, but use multiple frameworks to do so: nftw and fts. While nftw conforms to POSIX/SUSv3 and is widely available, fts is not conformant and less common, especially on non-glibc systems. The inconsistent framework usage hampers maintenance and portability of bpftool, in particular for embedded systems. Standardize code usage by rewriting one fts-based function to use nftw and clean up some related function warnings by extending use of "const char *" arguments. This change helps in building bpftool against musl for OpenWrt. Also fix an unsafe call to dirname() by duplicating the string to pass, since some implementations may directly alter it. The same approach is used in libbpf.c.

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.
