The kselftest test harness has traditionally not run the registered TEARDOWN handler when a test encountered an ASSERT. This creates unexpected situations and tests need to be very careful about using ASSERT, which seems a needless hurdle for test writers. Because of the harness's design for optional failure handlers, the original implementation of ASSERT used an abort() to immediately stop execution, but that meant the context for running teardown was lost. Instead, use setjmp/longjmp so that teardown can be done. Failed SETUP routines continue to not be followed by TEARDOWN, though.

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.
