Can you change the WARN() to a WARN_ONCE() too.

Generally, we prefer the "ONCE" variant if there isn't some intrisic
reason why we'd want to know about each event. If there is some load that
triggers this, do you care about _how_many_times_ it happens, or about the
fact that it happens in the first place? In this case, I think it's the
"happens in the first place" case - once you see it a single time, the
rest of the reports aren't that interesting.

And using the ONCE thing means that we know it's not going to spam the
logs.
