For SQPOLL rings tctx_inflight() always returns zero, so it might skip doing full cancelation. It's fine because we jam all sqpoll submissions in any case and do go through files cancel for them, but not nice. Do the intended full cancellation, by mimicking __io_uring_task_cancel() waiting but impersonating SQPOLL task.

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.
