Linux kernel source tree

The test robot reported two different problems when running the test_cpuset_prs.sh test. # ./test_cpuset_prs.sh: line 106: echo: write error: Input/output error # : # Effective cpus changed to 0-1,4-7 after test 4! The write error is caused by writing to /dev/console. It looks like some systems may not have /dev/console configured or in a writeable state. Fix this by checking the existence of /dev/console before attempting to write it. After the completion of each test run, the script will check if the cpuset state is reset back to the original state. That usually takes a while to happen. The test script inserts some artificial delay to make sure that the reset has completed. The current setting is about 80ms. That may not be enough in some cases especially if the test system is slow. Double it to 160ms to minimize the chance of this type of failure.

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.
