A lot of test cases in the file are related to the idle and unbalanced timers of resilient nexthop groups and these tests are reported to be flaky on slow machines running debug kernels. Rather than marking a lot of individual tests with xfail_on_slow(), simply mark all the tests. Note that the test is stable on non-debug machines and that with debug kernels we are mainly interested in the output of various sanitizers in order to determine pass / fail.

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.
