Jens Axboe 8165b56604 io_uring/cancel: add IORING_ASYNC_CANCEL_USERDATA
Add a flag to explicitly match on user_data in the request for
cancelation purposes. This is the default behavior if none of the
other match flags are set, but if we ALSO want to match on user_data,
then this flag can be set.

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.
