When enabling -Wunused warnings by building with W=1, I get an
instance of the -Wunused-but-set-parameter warning in the io_uring code:
fs/io_uring.c: In function 'io_queue_async_work':
fs/io_uring.c:1445:61: error: parameter 'locked' set but not used [-Werror=unused-but-set-parameter]
1445 | static void io_queue_async_work(struct io_kiocb *req, bool *locked)
| ~~~~~~^~~~~~
There are very few warnings of this type, so it would be nice to enable
this by default and fix all the existing instances. As the assignment
serves no purpose by itself other than to prevent developers from using
the variable, an easy workaround is to remove the assignment and just
rename the argument to "dont_use".
Fixes:

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.
