RV per-task monitors are implemented through a monitor structure
available for each task_struct. This structure is reset every time the
monitor is (re-)started, to avoid inconsistencies if the monitor was
activated previously.
To do so, we reset the monitor on all threads using the macro
for_each_process_thread. However, this macro excludes the idle tasks on
each CPU. Idle tasks could be considered tasks on their own right and it
should be up to the model whether to ignore them or not.
Reset monitors also on the idle tasks for each present CPU whenever we
reset all per-task monitors.

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.
