There are a few of those:
io_uring/fdinfo.c:170:16: warning: declaration shadows a local variable [-Wshadow]
170 | struct file *f = io_file_from_index(&ctx->file_table, i);
| ^
io_uring/fdinfo.c:53:67: note: previous declaration is here
53 | __cold void io_uring_show_fdinfo(struct seq_file *m, struct file *f)
| ^
io_uring/cancel.c:187:25: warning: declaration shadows a local variable [-Wshadow]
187 | struct io_uring_task *tctx = node->task->io_uring;
| ^
io_uring/cancel.c:166:31: note: previous declaration is here
166 | struct io_uring_task *tctx,
| ^
io_uring/register.c:371:25: warning: declaration shadows a local variable [-Wshadow]
371 | struct io_uring_task *tctx = node->task->io_uring;
| ^
io_uring/register.c:312:24: note: previous declaration is here
312 | struct io_uring_task *tctx = NULL;
| ^
and a simple cleanup gets rid of them. For the fdinfo case, make a
distinction between the file being passed in (for the ring), and the
registered files we iterate. For the other two cases, just get rid of
shadowed variable, there's no reason to have a new one.

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 reStructuredText 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.
