Sorry for the slow reply - I'm off at the moment so my latency is high.

Which caller is breaking which tests?

Reverting 21c05ca88a54 is easy, but there's no clean point to do it: the
warning is in the wq tree while the caller fixes are scattered across several
subsystem trees, and there's no reasonable way to synchronize all of that
outside mainline. If it's a specific caller breaking a test, fixing that one
is the better path.

Thanks.
