This pull request contains: - Fix for a file ref leak for registered ring fds - Turn the ->timeout_lock into a raw spinlock, as it nests under the io-wq lock which is a raw spinlock as it's called from the scheduler side - Limit ring resizing to DEFER_TASKRUN for now. We will broaden this in the future, but for now, ensure that it's only feasible on rings with a single user - Add sanity check for io-wq enqueuing Please pull!
