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&amp;#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.
