Rather than do per-tw checking, which needs to dip into the task_struct for checking flags, do it upfront before running task_work. This places a 'cancel' member in io_tw_token_t, which is assigned before running task_work for that given ctx. This is both more efficient in doing it upfront rather than for every task_work, and it means that io_should_terminate_tw() can be made private in io_uring.c rather than need to be called by various callbacks of task_work.

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 reStructuredText 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.
