With the increase number of tests, one CI instance, using a debug kernel config and not recent hardware, takes around 10 minutes to execute the slowest MPTCP test: mptcp_join.sh. Even if most CIs don't take that long to execute these tests -- typically max 10 minutes to run all selftests -- it will help some of them if the timeout is increased. The timeout could be disabled but it is always good to have an extra safeguard, just in case. Please note that on slow public CIs with kernel debug settings, it has been observed it can easily take up to 45 minutes to execute all tests in this very slow environment with other jobs running in parallel. The slowest test, mptcp_join.sh takes ~30 minutes in this case. In such environments, the selftests timeout set in the 'settings' file is disabled because this environment is known as being exceptionnally slow. It has been decided not to take such exceptional environments into account and set the timeout to 20min.

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.
