Caleb Sander Mateos dd386b0d5e io_uring/uring_cmd: correct io_uring_cmd_done() ret type
io_uring_cmd_done() takes the result code for the CQE as a ssize_t ret
argument. However, the CQE res field is a s32 value, as is the argument
to io_req_set_res(). To clarify that only s32 values can be faithfully
represented without truncation, change io_uring_cmd_done()'s ret
argument type to s32.

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.
