Pavel Begunkov ea011ee102 io_uring: protect cq_timeouts with timeout_lock 
Read cq_timeouts in io_flush_timeouts() only after taking the
timeout_lock, as it's protected by it. There are many places where we
also grab ->completion_lock, but for instance io_timeout_fn() doesn't
and still modifies cq_timeouts.
