If IORING_SETUP_COOP_TASKRUN is set to use cooperative scheduling for running task_work, then IORING_SETUP_TASKRUN_FLAG can be set so the application can tell if task_work is pending in the kernel for this ring. This allows use cases like io_uring_peek_cqe() to still function appropriately, or for the task to know when it would be useful to call io_uring_wait_cqe() to run pending events.

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.
