Smatch complains about returning negative error codes from a type bool function. kernel/cgroup/cpuset.c:705 cpu_exclusive_check() warn: signedness bug returning '(-22)' The code works correctly, but it is confusing. The current behavior is that cpu_exclusive_check() returns true if it's *NOT* exclusive. Rename it to cpusets_are_exclusive() and reverse the returns so it returns true if it is exclusive and false if it's not. Update both callers as well.

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.
