We should not be completing requests from a task context that has already undergone io_uring cancellations, i.e. __io_uring_cancel(), as there are some assumptions, e.g. around cached task refs draining. Remove iopolling from io_ring_ctx_wait_and_kill() as it can be called later after PF_EXITING is set with the last task_work run.

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.
