The socket read/write functions deal with O_NONBLOCK and IOCB_NOWAIT just fine, so we can flag them as being FMODE_NOWAIT compliant. With this, we can remove socket special casing in io_uring when checking if a file type is sane for nonblocking IO, and it's also the defined way to flag file types as such in the kernel.

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.
