If tracing is disabled for some reason (traceoff_on_warning, command line, etc), the ftrace selftests are guaranteed to fail, as their results are defined by trace data in the ring buffers. If the ring buffers are turned off, the tests will fail, due to lack of data. Because tracing being disabled is for a specific reason (warning, user decided to, etc), it does not make sense to enable tracing to run the self tests, as the test output may corrupt the reason for the tracing to be disabled. Instead, simply skip the self tests and report that they are being skipped due to tracing being disabled. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.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.
