The mentioned test measures the transfer run-time to verify that the user-space program is able to use the full aggregate B/W. Even on (virtual) link-speed-bound tests, debug kernel can slow down the transfer enough to cause sporadic test failures. Instead of unconditionally raising the maximum allowed run-time, tweak when the running kernel is a debug one, and use some simple/ rough heuristic to guess such scenarios. Note: this intentionally avoids looking for /boot/config-<version> as the latter file is not always available in our reference CI environments.

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.
