Commit 978e5c19dfefc271e5550efba92fcef0d3f62864 upstream. This bug was introduced in commit950e79dd73("io_uring: minor io_cqring_wait() optimization"), which was made in preparation foradc8682ec6("io_uring: Add support for napi_busy_poll"). The latter got reverted incb31821673("Revert "io_uring: Add support for napi_busy_poll""), so simply undo the former as well.

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.
