Patch series "selftests/mm: Add -Wunreachable-code and fix warnings".
Add -Wunreachable-code to selftests and remove dead code from generated
warnings.
This patch (of 2):
Enable -Wunreachable-code flag to catch dead code and fix them.
1. Remove the dead code and write a comment instead:
hmm-tests.c:2033:3: warning: code will never be executed
[-Wunreachable-code]
perror("Should not reach this\n");
^~~~~~
2. ksft_exit_fail_msg() calls exit(). So cleanup isn't done. Replace it
with ksft_print_msg().
split_huge_page_test.c:301:3: warning: code will never be executed
[-Wunreachable-code]
goto cleanup;
^~~~~~~~~~~~
3. Remove duplicate inline.
pkey_sighandler_tests.c:44:15: warning: duplicate 'inline' declaration
specifier [-Wduplicate-decl-specifier]
static inline __always_inline

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.
