Some applications like to start small in terms of ring size, and then ramp up as needed. This is a bit tricky to do currently, since we don't advertise the max ring size. This adds IORING_SETUP_CLAMP. If set, and the values for SQ or CQ ring size exceed what we support, then clamp them at the max values instead of returning -EINVAL. Since we return the chosen ring sizes after setup, no further changes are needed on the application side. io_uring already changes the ring sizes if the application doesn't ask for power-of-two sizes, for example.

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.
