A single partition setup and tear-down operation can lead to multiple rebuild_sched_domains_locked() calls which is a waste of effort. This can partly be mitigated by adding a flag to suppress the rebuild_sched_domains_locked() call in update_cpumasks_hier(). Since a Boolean flag has already been passed as the 3rd argument to update_cpumasks_hier(), we can extend that to a full flag word. The sched domain rebuild suppression is now enabled in update_sibling_cpumasks() as all it callers will do the sched domain rebuild after its return later on anyway.

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.
