Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
io_uring: ensure task_work gets run as part of cancelations<br />
<br />
If we successfully cancel a work item but that work item needs to be<br />
processed through task_work, then we can be sleeping uninterruptibly<br />
in io_uring_cancel_generic() and never process it. Hence we don&#39;t<br />
make forward progress and we end up with an uninterruptible sleep<br />
warning.<br />
<br />
While in there, correct a comment that should be IFF, not IIF.
