By default, io_uring will stop submitting a batch of requests if we run into an error submitting a request. This isn't strictly necessary, as the error result is passed out-of-band via a CQE anyway. And it can be a bit confusing for some applications. Provide a way to setup a ring that will continue submitting on error, when the error CQE has been posted. There's still one case that will break out of submission. If we fail allocating a request, then we'll still return -ENOMEM. We could in theory post a CQE for that condition too even if we never got a request. Leave that for a potential followup.

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.
