Currently, changes in "cpust.cpus" of a partition root is not allowed if it violates the sibling cpu exclusivity rule when the check is done in the validate_change() function. That is inconsistent with the other cpuset changes that are always allowed but may make a partition invalid. Update the cpuset code to allow cpumask change even if it violates the sibling cpu exclusivity rule, but invalidate the partition instead just like the other changes. However, other sibling partitions with conflicting cpumask will also be invalidated in order to not violating the exclusivity rule. This behavior is specific to this partition rule violation. Note that a previous commit has made sibling cpu exclusivity rule check the last check of validate_change(). So if -EINVAL is returned, we can be sure that sibling cpu exclusivity rule violation is the only rule that is broken.

README
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.
