When the boost kthreads are created on systems with nohz_full CPUs, the cpus_allowed_ptr is set to housekeeping_cpumask(HK_FLAG_KTHREAD). However, when the rcu_boost_kthread_setaffinity() is called, the original affinity will be changed and these kthreads can subsequently run on nohz_full CPUs. This commit makes rcu_boost_kthread_setaffinity() restrict these boost kthreads to housekeeping CPUs. Signed-off-by: Zqiang <qiang.zhang1211@gmail.com> Signed-off-by: Paul E.

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.
