Include GNU <execinfo.h> header only with glibc and provide weak, stubbed
backtrace functions as a fallback in test_progs.c. This allows for non-GNU
replacements while avoiding compile errors (e.g. with musl libc) like:
test_progs.c:13:10: fatal error: execinfo.h: No such file or directory
13 | #include <execinfo.h> /* backtrace */
| ^~~~~~~~~~~~
test_progs.c: In function 'crash_handler':
test_progs.c:1034:14: error: implicit declaration of function 'backtrace' [-Werror=implicit-function-declaration]
1034 | sz = backtrace(bt, ARRAY_SIZE(bt));
| ^~~~~~~~~
test_progs.c:1045:9: error: implicit declaration of function 'backtrace_symbols_fd' [-Werror=implicit-function-declaration]
1045 | backtrace_symbols_fd(bt, sz, STDERR_FILENO);
| ^~~~~~~~~~~~~~~~~~~~

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.
