KUnit aborts the current thread when an assertion fails. Currently, this is done conditionally as part of the kunit_do_failed_assertion() function, but this hides the kunit_abort() call from the compiler (particularly if it's in another module). This, in turn, can lead to both suboptimal code generation (the compiler can't know if kunit_do_failed_assertion() will return), and to static analysis tools like smatch giving false positives. Moving the kunit_abort() call into the macro should give the compiler and tools a better chance at understanding what's going on. Doing so requires exporting kunit_abort(), though it's recommended to continue to use assertions in lieu of aborting directly. In addition, kunit_abort() and kunit_do_failed_assertion() are renamed to make it clear they they're intended for internal KUnit use, to: __kunit_do_failed_assertion() and __kunit_abort() Suggested-by: Dan Carpenter <dan.carpenter@linaro.org> Signed-off-by: David Gow <davidgow@google.com> Reviewed-by: Miguel Ojeda <ojeda@kernel.org> Reviewed-by: Daniel Latypov <dlatypov@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
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.
