The current cpuset code passes a local isolcpus_updated flag around in a number of functions to determine if external isolation related cpumasks like wq_unbound_cpumask should be updated. It is a bit cumbersome and makes the code more complex. Simplify the code by using a global boolean flag "isolated_cpus_updating" to track this. This flag will be set in isolated_cpus_update() and cleared in update_isolation_cpumasks(). No functional change is expected.

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.
