Pavel Begunkov a126124c86 io_uring: annotate offset timeout races ...

commit 5498bf28d8 upstream.

It's racy to read ->cached_cq_tail without taking proper measures
(usually grabbing ->completion_lock) as timeout requests with CQE
offsets do, however they have never had a good semantics for from
when they start counting. Annotate racy reads with data_race().
