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