In order to facilitate debugging of issues from automated runs of the ftrace selftests turn on verbose logging by default when run from the kselftest runner. This is primarily used by automated systems where developers may not have direct access to the system so defaulting to providing diagnostic information which might help debug problems seems like a good idea. When tests pass no extra output is generated, when they fail a full log of the test run is provided. Since this really is rather verbose when there are a large number of test failures or output is slow (eg, with a serial console) this could substantially increase the run time for the tests which might present problems with timeout detection for affected systems, hopefully we keep the tests running well enough that this is not too much of an issue.

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.
