I was expecting xfs_reflink_end_atomic_cow() -> xfs_ilock() to be a
point of contention as well, but it does not show up. I suppose that it
because all those threads at completion stage are sleeping.
However, there is this which I omitted:

Ack, and unfortunately that series did not get much expert review.
