When workqueue cpumask changes are committed, the DISASSOCIATED workers affinity is not touched and this might be a problem down the line for isolated setups when the DISASSOCIATED pools still have works to run after the cpu is offline. Make sure the workers' affinity is updated every time a workqueue cpumask changes, so these workers can't break isolation.

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.
