Overflowed requests in io_uring_cancel_files() should be shed only of inflight and overflowed refs. All other left references are owned by someone else. If refcount_sub_and_test() fails, it will go further and put put extra ref, don't do that. Also, don't need to do io_wq_cancel_work() for overflowed reqs, they will be let go shortly 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.
