Linux kernel source tree

Add the tracing/osnoise/options file to control osnoise/timerlat tracer features. It is a single file to contain multiple features, similar to the sched/features file. Reading the file displays a list of options. Writing the OPTION_NAME enables it, writing NO_OPTION_NAME disables it. The DEAFULTS is a particular option that resets the options to the default ones. It uses a bitmask to keep track of the status of the option. When needed, we can add a list of static keys, but for now it does not justify the memory increase.

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.
