Since commit8f9ea86fdf("sched: Always preserve the user requested cpumask"), a successful call to sched_setaffinity() should always save the user requested cpu affinity mask in a task's user_cpus_ptr. However, when the given cpu mask is the same as the current one, user_cpus_ptr is not updated. Fix this by saving the user mask in this case too.

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.
